A MIDI controller musical instrument (80) with buttons (34) on two sensorboards (54,56) for controlling musical notes. The buttons (34) are arranged such that the most harmonious note combinations are played by fingering the most proximate button (34) combinations, and such that any given chord or scale can be played with a characteristic fingering pattern regardless of the range or key signature it is played in. The buttons (34) are placed such that the fingers and thumb of a hand can span the entire note range of the instrument (80). The buttons (34) that control the notes for any one key signature of the major scale are located within their own delimited area which does not contain buttons (34) controlling notes which are not part of that key signature. Notes are assigned to the buttons in such a way that the notes can be tuned to a wide variety of intonations without any consequent necessity to change the fingering patterns of the major scale or its modes. Separate sensorboards (54,56) are provided, which are mirror images of one another, such that fingering techniques for chords and scales can be mirrored by the two hands on the buttons (34) of the two playing surfaces. A convex playing surface is provided for each sensorboard (54,56) such that any part along the underside of a finger can be used to control a single button (34) or a row of buttons (42,44,46,48).
