Borrowing Chords from the Minor Scale-1

In a major key, often chords are borrowd from the 'parallel' minor key. So in the key of C (top stave) triads from the key of C minor may be used (bottom 2 staves)

ii - V - I Voice Leading The 'guide tones' in 7th chords are the 3rd and 7th - determining much of the character of the chord. In a ii-V-i progression the guide tones moves in a particularly elegant fashion (indicated)

6-note (11th chords)
Technically 11th chords include a root, 3rd, 5th, 7th, 9th and 11th. But '11' is also used to mean a 7th chord with an added 11th and no 9th (sometimes called 7add11) In addition, C11 is sometimes used as an (incorrect) shorthand for C9sus (R, 4, 5, ♭7, 9, ♭11) which has no 3rd. So the 'rare' 3rds ar bracketed below. The only common 'real' 11 chord is a min11 chord. #11 chords, however are often found. CŒ„Š11

The most common the above are Cm11, Csus11, Cmaj7(#11) and C7(#11) The latter two are often played without 5ths
7-note (13th chords) 13th chords technically contain root, 3rd, 5th, 7th, 9th, 11th and 13th (all 7 notes). However the 11th, unless on a min13 chord is very rarely intended, the 9th often (but not always) is, and unless indicated otherwise, as a natural 9th (D on a C13). Often a 13th chord just implies root, 3rd, 5th, 7th and 13th (ie C7add13) unless other degrees are stated (eg. C7(b9/13). Some but not all 13th chords are listed below, although you should be able to derive most from those below. CŒ„Š13

Tritone Substitution

Notice that the tritone substitution dominant chord now resolves down a semitone rather than a 5th, When a 'sub V' resolves down a semitone, let's analyse it with a dashed arrow. Similarly, a min7 or min7(b5) chord going down a semitone to a dominant chord gets a dashed bracket. IIm7

The 12- Bar Blues (Major) This is the very basic form based around I7, IV7 and V7. In this case I7 and IV7 are not considered secondary dominants as they do not have the same tendency to drop down a 5th. IV7 does not compel a resolution down a 5th and a piece can happily start and end on I7. Consider these dominant chords as idiomatic substitutions for I and IV (ot Imaj7 and IVmaj7) Note that the 12 bars are divided into 3 groups of 4 bars and that I, IV and V begin each group.

A 'jazz blues' takes the basic 12-bar blues form and embellishes it with secondary dominants. Bars 9 and 10 are typically IIm7 to V7 rather than V7 to IV7. Jazz-blues appear in many different forms and a typical example is given below. Although not written, 7th chords are often extended to 9ths, 11ths and 13ths for added colour I7

A complex jazz-blues progression is found in Charlie Parker's 'Blues For Alice' Even though there is much embellishment of harmony, the 3 basic 4-bar divisions are still in place (analysed below). A jazz analysis on the remaining chords will be helpful in unravelling its complexity.

Rhythm Changes This is the basic form of a rhythm changes. Deviations from this form occur but usually only minimally, through secondary dominants, passing diminished chords, tritone substitution, and related ii chords, to the dominants (particularly on the bridge). Maj7 and 6 chords are interchanged. This is a very important musical form to know by heart and you will recognize it in tunes such as The Flintstones,I've Got A Rhythm (Gershwin) and Jumpin' at the Woodside (Basie) A1

Note that the A sections are made of I-vi-ii-V implications (bars 1-2, 3-4 and 7-8) and a move to the IV then IVm6 from the parallel minor (bars 5-6). The bridge (B section) is a series of dominant chords descending 5ths before resolving to the original key (A 'cycle V'). As an exercise, identify with arrows all the resolving dominant chords, and with brackets, ii-V relationships. Hunt through jazz books to find and analyse rhythm changes. Anthropology, Oleo and Cotton Tail should get you started, and give you ideas for composition.

The IV-I and cycles
[email protected]
Much of the course material has focused on the V-I resolution, which is a fundamental component of tonal harmony. However in rock, pop, folk and modal music the IV-I is an equally important resolution. In classical music a IV-I resolution may be called a plagal cadence (The 'a-men' of a hymn)

In the bridge of a rhythm section for example, a series of dominant chords can be linked together, with each resolving down a 5th until they arrive at the I chord. A series of 4th-descending major triads may also be linked together. In the following sequence this pattern of major triads means that the first three chords are derived from the (C) natural minor scale, while the last 2 are from the major key. This exact sequence is used, in the key of E, in Jimi Hendrix's Hey Joe. Because a minor pentatonic scale can be played over both a minor and major key, it can be used over this entire sequence.

Since these intervals are not regular, we get a different pattern, and set of scale degrees depending from which of the 7 notes we start with. Each of these 7 starting points gives a 'mode' of the major scale and each has its own distinct and beautiful character, harmonic language and repertoire.
1. IONIAN Mode 1: Starting on the 1st degree: Ionian. In this case: C Ionian (C, D, E, F, G, A, B) with degrees (R, 2, 3, 4, 5, 6, 7) Identical, of course, to the major scale.

Writing Modal Chord Progressions
3
Since 7 modes are derived from one scale, they all share the same notes, and diatonic chords. How then can we make, for example D Dorian sound different to E Phrygian or F Lydian? Here are 5 methods to help write effective chord progressions. You don't need to use them all, but they are excellent principles.
1. Return to Root Chord often Use the 'root chord' regularly e.g. A minor or Aminor 7 in A Aeolian. This should occur on strong beats and bars (Every downbeat, or on every 2 or 4 bars for example) A aeolian: Root chord appears on the downbeat every 2 bars, solidifying mode.

2. Use a Pedal Tone By keeping the root of the mode constantly below diatonic chords, the mode is clearly established. F Lydian: Root of mode is kept as a pedal tone below diatonic chords, solidifying mode.

To avoid tonal references, chords can be constructed in 2nd, 4ths, 5ths and 7ths (and combinations there of) rather than just 3rds D Dorian: These chords are built in 4ths creating a more 'open'

5. Character Discover the 'character' chords of the mode - the chords that best describe the mode and show its unique identity - and use them. The melody should also contain the character notes of each mode, and return to the root often. The character notes and chords are described for 5 very useful modes below.
™™
Dorian
4
Let's look at the dorian mode, and choose A dorian so we can easily see its relationship to A natural minor. Since A dorian is derived from G major (the 2nd mode of G major) we'll use one sharp in the key signature. However A (and not G) should be considered the root, and we'll work out all scale degrees and chords with A as the root. The scale degrees are (R,2,b3,4,5,6,b7) A Dorian

Note that Dorian is different from natural minor in that it has a major 6th (not minor 6th) - in this case F# not F This is its character note. In fact it is the presence of both a minor 3rd and major 6th that gives much of Dorian's vibe. Here are the triads of A Dorian , together with a ('US') roman numeral analysis. Chords containing the character major 6th (F#) are underlined. The IIm and IV are the most common dorian modal chords (the VIº ir unstable and not commonly found) A Dorian A‹

And here are the 7th chords with roman numeral analysis. A very common and effective Dorian chord is the IV7, as it contains both the minor 3rd and major 6th of the mode. Of the seventh chords IIm7, IV7 are the most often used to describe Dorian modality, but most of the other diatonic chords may be found in progressions. In addition the Im6 is chord is often used.

The verses are Am Bm/A C/A Bm/A Oye Como Va - Santana (Am D7 -Im IV7)
Phrygian
5
Now Let's look at the 3rd mode, the phrygian mode, and choose A phrygian so we can easily see its relationship to A. Since this is derived from F major (the 3rd mode of F major) we'll use one flat in the key signature. However A (and not F) should be considered the root, and we'll work out all scale degrees and chords with F as the root. The scale degrees are (R,b2,b3,4,5,b6,b7) A Phrygian

There are may examples of the Phrygian mode in popular music, particularly when 'spanish' and sinister atmospheres are required. Here are a few: White Rabbit - Jefferson Airplane. (F#5 and G5 and the notes from F# phrygian are used) Symphony of Destruction - Megadeth (the opening riff uses E5, F5 and G5 from E Phrygian) The God That Failed - Metallica (Eb5, Fb5, Gb5, Bb5 from Eb Phrygian) War - Joe Satriani (E5 and Fmaj7(#11) from E phrygian)
Lydian

The 4th mode of the major scale, the Lydian mode, is often found in film soundtracks for its 'floating' and 'magical' quality. The lydian mode can be derived from C major from F to F. If we calculate Lydian with a root of C,we can easily see how it compares to a major scale. In this case we get an F# instead of an F. Lydian is a major scale with a raised (augmented) 4th. (R, 2, 3, #4, 5, 6, 7)

Note that Lydian is different from major in that it has an augmented 4th (not perfect 4th) - in this case F# not F This is the character note of Lydian which gives it its unique 'magical' quality. Here are the triads of C Lydian , together with a ('US') roman numeral analysis. Chords containing the character augmented 4th (F#) are underlined. The II and VIIm are the most common lydian modal triads (the #IVº if unstable and not commonly used) C Lydian

There are many examples of the Lydian mode in popular and film music, particularly when a floating and magical atmospheres are required. Here are a few moments from pop songs: Sara - Fleetwood Mac. (Opens with F, G/F and Am/F all from F Lydian) Man on the Moon - REM (the intro and verses use C major to Dadd11 from C Lydian) The Simpsons theme - Danny Elfman (One of the most famous lydian melodies of all time in C LydianIn fact some of the harmonic material implies Lydian dominant - a mode of melodic minor) The Riddle - Steve Vai (Open in E Lydian with an A# (sharpened 4th as the opening melody note) Other examples include Blue Jay Way - The Beatles, Every Little Thing She Does is Magic - The Police, All I need - Radiohead (C Lydian) The verses of Tonight, Tonight - Smashing Pumpkins.
Mixolydian
7
The 5th mode of the major scale, the mixolydian mode, is often found in rock and blues. It is also found in superficially 'eastern' influenced pop music due to its similarity with some Ragas. The mixolydian mode can be derived from C major from G to G. If we work out a mixolydian scale with a root of C,we can easily see how it compares to a major scale. In this case we get a B-flat instead of a B, so mixolydian is a major scale with a minot (flattened) 7th. (R, 2, 3, 4, 5, 6, b7)

So Mixoydian is different from major in that it has a minor (not major) 7th - in this case B-flat not B This is the character note of mixoydian which gives it its 'dominant' quality. In fact it is the combination of the major 3rd and minor 7th that sets it apart from all the other modes of the major scale. Here are the triads of C Mixolydian , together with a ('US') roman numeral analysis. Chords containing the character minor 7th (Bb) are underlined.

More 'pure' examples of mixolydian (when harmony and melody are both mixolydian) include: Norwegian Wood - Beatles. (E Mixolydian) Sweet Child of Mine - Guns and Roses and Sweet Home Alabama - Lynyrd Skynyrd (D, Cadd9, G D in verses and the notes of guitar intro are all from D mixolydian) Champagne Supernova - Oasis (A, A/G, A/F# and A/E - derived from A mixolydian) Other examples include Led Boots - Jeff Beck, Within You or Without You - Beatles,
Aeolian
8 The 6th mode of the major scale, the aeolian mode, is a common mode in rock and pop music when a mournful emotion is required. The aeolian mode can be derived from C major from A to A which gives us the following scale degrees. (R, 2, b3, 4, 5, b6, b7) A Aeolian

You'll notice that the aeolian mode is identical to the natural minor scale. However in a minor key, the 7th note of the scale is often changed to a leading tone (harmonic minor) which allows for V7 chord for example. The 6th degree is also sometimes changed, as in melodic minor. However the aeolian mode has a fixed minor 6th and minor 7th which gives it its particular character. Here are the triads of A Aeolian , together with a ('US') roman numeral analysis. Chords containing the character minor 6th (F) - distinguishing it from Dorian - are underlined the IIº (rarely used), IVm, VI.

Pentatonic Scales
©2010 Mermikides Pentatonics are hugely important scales in a wide range of musical styles. There are many 5 note scales in use, but the two most common are the major pentatonic and minor pentatonic and are shown below.

The major pentatonic is like a major scale but without the 4th and 7th. Note that the omitted 4th and 7th scale degrees are the ones with semitone relationships against a tonic triad, and the source of the most harmonic motion in the major scale. With the 4th and 7th omitted, the major pentatonic is a very neutral, singable and familiar scale.
The major pentatonic has 5 modes, the most common starts on the last note (the A here) and is called the minor pentatonic So the notes of C major pentatonic (C D E G A) are the same as A minor pentatonic (A C D E G)

The minor pentatonic is like a natural minor (aeolian) but without the 2nd or 6th (which have semitone relationships against a tonic minor triad) With the 2nd and 6th omitted, the minor pentatonic is an extremely useful, effective and commonly used scale.

PENTATONIC SCALES AND THE MODES The major scale has 7 modes, 3 major (ionian, lydian, mixolydian) 3 minor (dorian, phrygian and aeolian) and 1 dimished (locrian). Interestingly the 3 major modes all contain the major pentatonic, and only differ in terms of there 4th and 7th degrees. Similarly, the 3 minor modes all have the minor pentatonic in common, with their 2nd and 6th degrees differing.

Using Pentatonic Scales on Chords
One approach in using pentatonic scales over a chord sequence, is to use the pentatonic scale of the key over all the progression. For example if the sequence is in G major, then G major pentatonic may be used throughout. G major pentatonic

Major and Minor Blues Hexatonic scale The major and minor pentatonic scales may be embellished with an added note (making 6-note - or hexatonic -scales) These added notes gives the 'blues' scale an idiomatic bluesy quality.
Major Blues The Major Blues 6-note scale is created by adding a sharpened 2nd (minor 3rd) interval between the 2rd and 3rd degree. This gives the scale an idiomatic minor 3rd as well as major 3rd.

Minor Blues On page 1 we created a minor pentatonic scale by starting a major pentatonic from the last scale degree. We can do the same thing to the mMajor Blues, to create the minor blues scale. This is a minor pentatonic scale with an idiomatic raised 4th (flattened 5th).

The blues scales are embellished versions of their pentatonic counterpoints creating an idiomatic bluesy quality. They might be used wherever the pentatonic scale is - as described on page 3. So for example a progression in B minor can be melodicized with B minor blues, a G major progression with G major blues and a Dminor7 chord with D minor blues.
Parallelism Some harmonic progressions include one chord type (usually a 5, major triad or dom7 chord) that is moved in a 'block' to create non-diatonic progressions. Often this can be best explained as the 'block' harmonisation of a scale - often pentatonic -(regardless of diatonicism) Here are some examples.

Inversions and Basslines ©2011
[email protected]
So far we have been looking mainly at root inversion chords, however inversions are often used to create compelling (often step-wise) bass-lines. There are countless examples, a representative selection of which are below. You'll notice that some of these will include, but are not limited to, CESH elements.
1. I to V(1st inversion) I to V(1st inv) to vi creates a descending bassline: E.g. Let it be (Beatles) Tears in Heaven (Clapton - in A major) A Day In the Life (G major)

Rock and Soul Harmonic Devices ©2011
[email protected] Other than the diatonic, secondary dominant, modal, parallel and other harmonic functions covered in the first half of this course there are other common and effective techniques that ‘deviate’ from these theoretical foundations. Here we look at the II chord, interpolated IV, III, VII and VI chords, the Vsus9 and bVIIsus9 hybrid chords and sliding chords. Note that most of this terminology is coined here so don’t expect to hear the terms elsewhere. However you will find these devices used widely, and regardless of how they are named (if at all) it is very instructive and useful to understand and recognize them. The ‘non-functioning’ II or II7 chord. Although this may be seen as a V/V or V7/V there are times when it doesn’t have this function, acting more as a momentary Lydian implication (an example of modal interchange) – In these cases it is more appropriate to call it a II (or II7) rather than V/V (or V7/V). Examples: You’re all I need to get by – Marvin Gaye/Tammi Terrell. A:
A I
B II
Dm6 A iv6 I
School of Rock This use of II occurs in the following progression. D:
D I
E II
G IV
D I
Sometime a V/V is resolved – but with an intervening IV chord delaying the resolution. eg. V/V IV V I. This device of delaying a resolution to V we can call an interpolated IV for lack of a pre-existing term. Here’s a real-life example from Beck - We Live Again !5th resolutions Bb:
Bb I
Gm C vi V/V [---ii V---]
Eb IV
F V
Bb I
We can think of the C chord as a V/V here, partly because of the preceding ii chord, and partly because of the eventual resolution to the F. The difference
of this case from the II chord is subtle and a little subjective but it’s instructive to understand the differentiation. Resolution through chromatic ascent of III (or III7) and VII (or VII7) In ‘standard’ diatonic harmony, major or dominant chords built on the 3rd or 7th degree of a major scale III have a secondary dominant function: V7/VI or V7/III respectively. !5th : C I
E(7) V/VI
Am vi
C I
B(7) V/III
Em iii
!5th :
However there are many cases when these are used as approaches to IV and I respectively, ascending a semitone, rather than descending a 5th. "min2nd C I
E(7) III(7)
F IV
B(7) VII7
C I
"min2nd C I
The III-IV (and III7-IV) resolution actually makes good harmonic sense: If we take the key of C as an example. The non-diatonic III - or III7 – chord (E or E7) introduces one non-diatonic note: the G#. This accidental resolves to an A (the 3rd of the F(IV) chord) rather than the root of the VIm chord in its more ‘functional’ resolution. This resolution of the non-diatonic note has a satisfying elegance, and is quite common in rock/pop tunes. A couple of examples: C E7 F I III IV (Imagine – John Lennon – Just after ‘You may say I’m a dreamer’) or G B7 C A7 (Sitting on the Dock of Bay – Otis Redding verse – which also uses the II7 chord)
The VII-I on the other hand has a more parallel feel, with the 2 non-diatonic notes (the F# and D# of B in the key of C) both resolving upwards. The VII/I - in combination with II – appears here: Bb C A Bb I II VII I (We Live Again - Beck) The VI chord The VI chord is a non-diatonic triad that doesn’t always fall into a V/II function. Since the VI chord isn’t a parallel minor or common modal ‘borrowed’ chord, what can it mean? One possible explanation is that it is simply the replacement of the expected VI minor chord with a major chord type. Indeed it seems to be used like a VIminor chord- C A instead of C Am for example – as if it’s the I major of the relative minor key. Odd I know. Whatever the explanation, the VI chord has a really distinctive and surprising sound. An example in a well-known tune is the ‘whistle section’ of Sitting on the Dock of Bay – Otis Redding: A looping 4-bar section: 3 bars of G (I), one bar E (VI). Softening the V7-I The V7 has a very implicit function in tonal harmony, the resolution to I is particularly expected, which is due to: 1) 2) 3) 4)
The bass on the 5th degree (which ‘wants’ to resolve down a 5th) The leading tone (7th degree) which ‘wants’ to resolve up. The 4th degree of the scale that ‘wants’ to resolve down. It contains a tritone interval (which ‘wants’ to be somehow resolved)
Sometimes we don’t want all of these devices – they might seem to twee and obvious when used together. The tritone substitution - for example - drops the first characteristic, and keeps the other three. We could soften the cadence by removing the 4th degree (and thus the tritone) leaving only item 1) and 2). This is a V-I cadence. On the other hand if we do not include the leading tone (using the root instead) we also erase the tritone dissonance, and only have items 1) and 3). This is a Vsus7-I cadence. Removing the leading tone and the 4th degree – also removes the tritone and creates the relatively soft Vsus-I. These degrees of softness of V-I resolution are useful and commonly used. V7–I Hard cadence !
subV7 V-I
Vsus7–I
Vsus – I " Soft cadence
The IV over V bass hybrid chord There is another common - and very effective - device to create an alternative cadence. This involves taking the first item 1) from the list above and merging it with the softer IV-I (plagal cadence). This involves a IV chord with a V bass. This device of using a chord with a non-chord tone is known as a hybrid chord – and there are many beautiful examples. In this case we are taking the IV chord and putting a V root in the base, So in the key of C this would be F/G. The F/G chord (G, F, A, C) can be considered as a Vsus9 (without a 5th). This idea can expanded for example the IV-I cadence can be elaborated as a IVmaj7–I – by using the 7th form of the chord. An Fmaj7/G (G F A C E) can also be considered a Gsus13 (with no 5th) a more ‘open’ and ‘colourful’ sound than Gsus9. One final example (althought there are many more) is to use a minor iv-I cadence – that we’ve seen before as a borrowing from the parallel minor, but with the V degree in the root of the iv chord : Fm/G (G, F, Ab, C) which creates a Gsus(b9) implication. This technique is a simple way of creating cadences that have the sense of a V7-I resolution but with more harmonic sophistication and ‘openness’. See Blame it on the Boogie as one of many examples where an Ab/Bb (Bbsus9) chord is used at the end of the verse and a Cbmaj7/Db (Dbsus13) in the chorus. Sliding Chords We’ve looked at parallelism before, where one chord type is moved in a usually systematic fashion creating moments of non-diatonicism (e.g. a series of major chords moved in a minor pentatonic scale). There is a special case of parallelism that is quite short and specific: When two diatonic chords are the same type and a whole tone apart, sometimes a chromatic non-diatonic passing chord of the same type can be interpolated – which we can call a ‘sliding chord’ – underlines below. E.g. If I Ain’t Got You – Alicia Keys G:

Upper Structure Major Triads
[email protected] As we've seen briefly in Rock & Pop Devices, basic triads - when placed over non-chord tones - can create sophisticated harmonic/modal implications while retaining a sense of simplicity. Here's a roster of upper structure chords (major, minor and 7th) with their harmonic/modal implications in relation to the bass note and - where appropriate - the triad. The implications depend very much on context, remember it is how these devices are heard - not dispassionately analysed - that is important. These devices are used in a wide range of music from Stevie to Stravinsky and the best way to learn them is to identify them in music of others and use them in your own writing. These are termed variously as upper structure triads, slash or hybrid chords. Basic inversions are included from completeness.

Complete Track Analysis ©2011
[email protected] With the important elements of harmony in place, it’s time to integrate these aspects into a complete picture of a track1. Here’s a very brief but pertinent checklist of various musical features that when taken together can help further musical understanding and in turn enhance creativity. These concepts and questions are all worth considering when approaching a track analysis. In this course we’re looking mainly at the pure harmonic mechanics, rather than lyrical interpretation and song structure, but we must remember that the impact of a track is multi-faceted, so understanding these other important elements will give a more nuanced – and more applicable – understanding of popular music harmony. Many of these concepts may be addressed to the score of the track. However it is very important that an analysis is conducted through the receptive listening of music. The musical practice is about the listening and creative process, and although notation is an extremely useful way to communicate, consider and conceptualise a track, it is only a tool in order to enhance, and not replace, the musical experience.
The Basics Style – Genre(s) - Instrumentation - Production Tempo – Time Signature - Groove – Rhythmic Subdivision - Feel Lyrical content – Impact – Vibe - ’Meaning’ Do any of the above change during the course of the track?
1 We’ll use the term ‘track’ to denote any relevant composition be it pop song, metal instrumental, jazz standard or folk tune. ‘Piece’ or ‘work’ is a tad pretentious, ‘song’ is an odd term for instrumental music and ‘tune’ is a bit ambiguous. So, for convenience, ‘track’ it is. We needn’t get distracted further with semantics, or get overly fussy with terms, so that said, let’s just get on with it.
©2011 Milton Mermikides Complete Track Analysis
2
Structure Can the track be divided into logical sections using such terms as Intro, Verse, Prechorus, Chorus, Instrumental Solo, Bridge or ‘Middle 8’, Instrumental Interlude and Outro? Can you provide a simple map of the sections? Can that map be further simplified using repeats, DS, DC, Coda, Fine etc? When sections occur more than once, how are they varied, truncated, extended, reinterpreted, transposed or otherwise reinterpreted? Do any of the sections share features? For example does the guitar solo have the same chords as the verse? Sketch, or write out the basic form. Here’s an example, it doesn’t have to be exactly like this, any way that communicates the whole structure as simply and clearly as possible.

Key and Harmony What is the key area, mode or tonic note of the track? Does it change through modulation? If modulations occur are they simply shifting previous material to a new key or does new material accompany the shift? Are the key modulations closely related to the original key (eg. F to Aminor) or a parallel shift (Cmajor to Db major)? Is the modulation ‘pivotal’ (by using chords that are related to both keys) or is it ‘direct’ and ‘unprepared’? Once a modulation occurs, does the track end in this new key, return to the original, or continue to another –maybe similar – modulation? Does the chord progressions fit into any of the harmonic devices covered in this course? (E.g. Diatonicism, parallel major/minor/borrowing, inversions, secondary dominants, Blues chords, parallelism, pedal tones etc.) Can the progression be generalized and quickly absorbed using roman numeral (or similar) analysis (e.g. i – iv – i - V7). Harmony is of course, is the main content of this course so we needn’t repeat it here. However it’s important to remember that: a) As noted before, harmony is just one of several important musical aspects and it its interaction with other features that creates musical impact. b) All the harmonic concepts presented in the course are only important because they are used and can be reapplied effectively. Harmonic analysis is not an intellectual diversion like sudoko, it has direct musical relevance.
Melody There will be supporting material for the study of melody but here are some salient points that will help understand how to approach the analysis and creation of melodies. Listen (and look) at the entirety of the melody. Can it be broken into logical phrases? Often this can be done at a few levels: 1) The entire melody 2) The melody at each of the structural sections (see Structure) 3) Phrase groups within each section 4) Commonly used intervals/motifs within phrases. For each of the above it can be useful to explore:
©2011 Milton Mermikides Complete Track Analysis
4
1) Range and contour. What is the highest and lowest pitches in the melody (or phrases)? When does the peak occur, what is the overall shape of the melody, or contours of the phrases? How and where do any of these contours repeat, perhaps transposed? When a phrase is repeated closely, look out for any variations – particularly at the end of phrases. When the melody is played in isolation which phrases feel unresolved (‘questions’) and which feel like resolutions (‘answers’)? 2) How are phrases separated? Do phrase lengths change? 3) Is the melody (or are the phrases) drawn from a common scale/mode (is it heptatonic, hexatonic or pentatonic?) Does it does change at any point and if so, how and when? 4) What intervals does the melody make against the chords? Are they all chord tones? How are non-chord tones resolved if at all? When melodic shapes are repeated against different chords, does the melody stay the same (changing the intervals against the chords) or is the melody transposed or sequenced (perhaps preserving the same intervals)? 5) What are the most distinguishable, characterizing and memorable aspects of the melody?
The Big Picture You should now be able to combine the important aspects from all of the above into a complete picture. Your final project will include such an analysis of a complete track and a composition (with commentary) of your own. This process will help to understand the track in its entirety, improving your musical perception, appreciation and ability to create your own music, which in turn will increase your understanding of music. Keeping this positive cycle of theory-practice active will improve your understanding, communication, creativity and enjoyment of music. Not a bad deal.
Melody and Harmony
[email protected] As mentioned, in 'Complete Track Analysis', harmony can only be fully understood in relation to other musical considerations. This handout looks at melody's relation to harmony in a little more detail. Remember that context is crucial in music, so none of the following are immutable laws, just helpful guidelines and incentives to notice the most salient features. Music is multi-dimensional, there is expressive power in timbre, rhythm, groove, melody and harmony as isolated features, and in their complex interactions. First we look at some expressive features of melody in itself, and then its interaction with melody.

The layout above gives a general impression of how the notes of a major scale compare in terms of resolution level. This explains why we see certain shapes of melodies, and how phrase endings differ between phrases of a melody. We may also extend this concept of melodic tension to include non-diatonic notes, an impression is given below. Although subjective, there are technical reasons for the rough layout below. However, although we are still considering melody as independent of harmony, the following should be taken only as an approximate guide - context of surrounding melody notes, implied keys, phrasing and rhythm are still critical.

So far we have looked as melody as separate (as far as possible) from harmonic context. This is an important component of analysis (and context) and establishes the sense of expression in an isolated melody. The following extract (Beatles-Across The Universe) gives a simple general impression of the melodic tension in the melody. Note how a phrase is repeated almost identically, except for the ending which is at first unresolved, and then resolved.

If we look at the chords in isolation we get another pattern of tension and release, which sometimes correlates with the melodic tension and sometimes doesn't. They differ most notably here when the melody resolves at the end of the 2nd phrase while the harmony holds down a colourful and unresolved subdominant minor (iv) chord. This is an example of the multi-level property which makes music so endlessly fascinating and absorbing. Now we've looked at melodic tension, and also mentioned that it exists in relationship (but not direct correlation) with a sense of harmonic resolution, we now turn our attention to consonance and dissonance, how particular melody notes are heard against specific chords - sometimes referred to as the vertical relationship.
Consonance and Dissonance
3
The following diagrams give an indication of the level of consonance/dissonance over a few common chords. Remember context is important - for example - whether the note is diatonic, or if it stressed rhythmically or left unresolved will alter the sense of dissonance. Still, it is certainly worth trying these out yourself and considering this important mechanism in both your analysis and composition.

The above guide treats chords in isolation, divorced from harmonic context - whether the chord is a I, ii or IV for example. A general persepective of consonance and dissonance which includes this element might be represented thus: Consonant Chord Tones (CTs) Common
Dissonant Diatonic note whole tone or above nearest chord tone
Non-diatonic note whole tone or above nearest chord tone
Diatonic note semi tone above nearest chord tone
Non-diatonic note semi tone above nearest chord tone Rare
There are some exceptions to this guide. Most notably the minor 3rd, which is a very commonly used and stylistically fundamental non-diatonic note in a major or blues context.

Melody on Harmony
The study and understanding of melody is a life-long pursuit, but let's look at a succinct representative selection of broad concepts addressing how melody may effectively integrate with harmony, how dissonance is resolved and common 'tensions.'
Chord-Tone Melody In the following example (All The Things You Are - Hammerstein/Kern) the melody is constructed entirely from chord tones (CTs) from the underlying chord sequence. Chord degrees (not specifically major minor) are given.

Diatonic Sequence, Passing Tones and CT pivots There are 3 powerful devices in the following extract (Autumn Leaves - Kosma/Mercer) 1) Diatonic sequence: A fixed pattern of chord degrees are moved through a harmonic progression. 2) Passing Tone: Stepwise resolution of NCTs between CTs. Note how the NCTs here (9ths) are approached from, and resolved to, CTs using a diatonic scale. 3) Chord-tone pivots (a new term): Note how held notes change from one CT to another CT of a new chord.

A NCT is approached by a skep and resolved by a step (usually but not always in the opposite direction) Appoggiatura. A NCT may also be approached by a step from a CT and resolved by a skip (usually in the opposite direction) This is very similar to the idea of escape tone, where the skip occurs on a harmonic change. NCTs are usually but not always (see bar 3) diatonic.

Chromatic 'Accepted' Passing Tone NCT. to...
The last note here introduces the idea of 'accepted' non-chord tones. Clearly the 9th sounds just fine and may be happily left unresolved. Actually in Jazz such melody notes are often 'written in' to the harmony, a C9 in this case. But this isn't always appropriate, and often in popular music these notes are clearly not included in the harmonic accompaniment, doing so can make the harmony overly fussy and weaker. So how do we decide what is 'acceptable' in terms of NCTs? A musical ear is always the best judge and context and style are important and sometimes 'outness' is desired. (Just listen to Zappa, Blur or King Crimson for perfectly judged 'wrong' notes) Page 3 of this section (Consonance and Dissonance) will provide some theoretical context to the degrees of dissonance in melody, not forgetting that placement on strong or weak beats - the rhythmic emphasis of NCTs is crtitical. Using dissonant notes is not necessarily bad (although involves skill) and perfectly 'correct' notes does not necessarily produce good music. However an awareness of the consonance/dissonance continuum is hugely valuable. This particulary topic is vast but we will end with just one further illustrative example:
Fixed Melody and Changing Harmony A powerful device is to use a fixed melody, over a changing harmonic sequence. The melody may create NCTs (in this case very common ones) and there is an interesting musical effect of hearing similar material in different harmonic contexts. In a way this is the opposite of the sequence, which changes melody to maintain similar chord degrees over changing harmony. From C-Jam Blues - Duke Ellington C7

The End and the Beginning Often dismissed by people don't know any better as 'simple', popular music harmony is a complex and fascinating mix of concepts and cultural influences that are endlessly interesting, effective and inspiring. Do remember that harmony lies in a complex interrelationship with all other music parameters and how its used - and its musical effect - is determined by context rather than theoretical abstraction. I graduated from a 4-year degree in 1996 which I approached with passion and commitment, since then there has not been a day that I have not thought about, played or composed music, I've even completed a PhD in composition, and I am still discovering fascinating and rewarding insights about understanding and using 'simple' harmony. I wish you the same enjoyment and satisfaction.
