ABSTRACT:
A plurality of display units are provided in corresponding relations to individual performance keys. A table stores, for each of a plurality of chords, information which defines plural groups of notes that are always available for the chord, temporarily available (e. g., a tension note) for the chord and unavailable for the chord. In response to designation of a chord according to a chord progression, the information is read out from the table and the display units are controlled according to the read-out information so as to dislay in different forms, depending on which one of the groups the performance keys corresponding to the display units correspond to. A performer can operate a desired key in consideration of different display forms. Thus, there is provided a music performance assisting system which is suited for use in executing an adlib performance with notes well conforming to a designated chord.
