A device for use in an electronic musical instrument, in which data representing musical factors such as a tempo, a pitch and a timbre are changed at each repetition of an automatic performance, to thereby automatically effect variable automatic performances. Further, data representing a chord type and a chord root are input by a character-data input device such as a ten-key pad, and thus a chord input operation is facilitated, and moreover, a complicated finger manipulation becomes unnecessary. Furthermore, data representing chord types is input by at least one of the pitch input devices, and data representing chord roots is input by at least one of the other pitch input devices, and thus a chord performance is facilitated. Further, many types of chords can be performed, and moreover, the type and the root of a chord to be next performed, as well as those of a chord currently performed, are displayed, and thus the content of the chord to be next performed can be known in advance, whereby a chord performance can be smoothly effected.
