Abstract
In an electronic musical instrument for automatically a adding duet note, an apparatus, which can reduce the capacity of a memory for storing data used as a basis for selecting a duet note to be added, is disclosed. A chord depressed at a keyboard is specified by a chord specifying means, and a depressed melody note (highest note) is detected by a note detection device. According to these notes, duet note data, which can be added, is read out from a chord-notes weighting information storage area on the basis of chord constituting notes, and another duet note data, which can be added, is read out from a note weighting information storage area according to a relative note data of the highest note relative to the root note of the chord. These readout duet note data are subjected to a calculation, thus selecting a duet note. Therefore, duet note data corresponding in numbers to chords and relative notes need only be stored in the memory, thus reducing the capacity of the duet note data memory.
