Abstract: An automatic performing apparatus and an electronic instrument with which a user can carry out an automatic musical performance, even for a complicated arrangement, simply by providing external events at certain intervals or corresponding only to a melody. In such an electronic instrument, at the time of execution of the automatic musical performance, the keyboard events are provided at intervals of one beat. Then, the automatic musical performance is progressed within a certain section corresponding to each of the provided keyboard events. Otherwise, at the time of execution of the automatic musical performance, the keyboard events are provided at the timing of a melody. Then, musical tones for the corresponding melody are generated, while those for accompaniments following the melody are also automatically generated. Furthermore, the tempo of the automatic musical performance is set on the basis of intervals between the keyboard events.

Abstract: 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.

Abstract: A device for correcting a timing of music playing information including a determining unit and a correcting unit, the correcting unit corrects the timing of the change of the performance of a piece of music, which is outside the range of short time data, to a timing within the range of the short time data, in response to a determination by the determining unit.
