ABSTRACT:
A key signature actuator for musical keyboard eases playing from music written with a difficult key signature by automatically actuating the sharps or flats in the key signature. Musical notes are associated with keyboard landmarks positioned along the keyboard rather than with fixed digitals, and the landmarks are moved bodily up or down the keyboard to identify different sequences of digitals to associate with the notes. An automated key signature actuator moves a keynote of the desired key signature to the keyboard position normally occupied by middle C, at the same time changing the overall pitch of the musical output to make the keynote sound as intended. The changeable keyboard landmarks are also used in the teaching of music and to assist the playing of music written in different notations.
