    摘要： An apparatus for the translation of musical chords from one key to another key. Both the electronics and mechanical embodiments of the invention permit the user to translate a musical score in a source key to a target key by identifying the appropriate chords for the target key. In the mechanical embodiments, the source key is physically aligned with the target key. This positions the chords to also be in aligned or associated with each other. In the electronics embodiment, the user establishes the source key and the target key to establish the chord mapping. In one electronic embodiment, the operator also identifies the source chord for the absolute identification of the targeted chord. Optionally, a listing of the chord mapping is printed for later reference or for transcription onto the musical score.

    摘要： A key signature actuator for a musical keyboard eases playing from music written with difficult key signatures by automatically actuating the sharps or flats in the key signatures. The keyboard has five back digitals per octave span, like the traditional keyboard, except that the back digitals are de-emphasized as landmarks by making them light gray, and musical notes are associated with movable landmarks, rather than with fixed digitals. When in written music a key signature is indicated, the landmarks are electronically shifted so that the key note of that key signature is played by a tonic digital (a fixed front digital to the immediate left of a group of two back digitals). At the same time the tonic digital is made to sound the key tone corresponding to that key signature by adjusting the overall pitch of the musical output by means of a uniform pitch changer. The number of electrically changeable landmark elements is minimized and binary coding is used to simplify the electrical connections. Apparatus for moving the landmarks mechanically is also disclosed.
