An electronic

keyboard (also

called digital

keyboard, portable

keyboard, or home keyboard) is an electronic or digital keyboard instrument. An isomorphic keyboard is a musical input device consisting of a twodimensional grid of note-controlling elements (such as buttons or keys) on which any given sequence and/or combination of musical intervals has the "same shape" on the keyboard wherever it occurs – within a key, across keys, across octaves, and across tunings. An enharmonic

keyboard is

a musical

keyboard,

where enharmonically equivalent notes do not have identical pitches. A conventional keyboard has, for instance, only one key and pitch for C sharp and D flat, but an enharmonic keyboard would have two different keys and pitches for these notes. A keytar is a relatively lightweight keyboard (with or without a builtin synthesizer) that is supported by a strap around the neck and shoulders, similar to the way a guitar is supported by a strap. Keytars allow players a greater range of movement compared to conventional keyboards, which are placed on stationary stands.
