Abstract: 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.

Abstract: 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 so that any given chord or scale may 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 ether hand can simultaneously span the entire note range of the instrument (80). The buttons (34) that control the notes of a given major scale may be fingered within the boarders of a common area that does not contain buttons (34) for the notes that are not part of that scale. The buttons (34) are organized so that the notes can be tuned to a wide variety of intonations without altering the fingering of the major scale or its modes.
