Abstract
An electronic musical instrument which produces counter melody automatically selects one from among chord constituting tones in a predetermined priority order and produces a tone of the same note as the selected tone as a counter melody tone. This electronic musical instrument further comprises a chord type detector for detecting a chord type of a performed chord besides a chord designation detector for detecting the fact that the chord has been designated, a counter melody tone determining circuit for selecting one from among the chord constituting tones and sound system for producing the counter melody tone. The predetermined priority order is determined in accordance with the detected chord type. This dependence on chord type make it possible to produce a counter melody tone which is more rich in music.
