Abstract

In an automatic performance apparatus for creating music piece data by combining automatic performance pattern data, a plurality of automatic performance patterns are stored in advance, and display elements corresponding to these automatic performance patterns are prepared. An operation for displaying these display elements on a display device and connecting them by lines is performed. The order of automatic performance patterns is determined in correspondence with the order of the elements connected by the lines. With this operation, music piece data can be easily created and modified. In an automatic accompaniment edit apparatus for creating/editing chord progress data for an automatic accompaniment operation, chords or chord progress patterns suited for each style are stored in correspondence with a plurality of styles. When a user selects a style, chords or chord progress patterns suited for the selected style are informed. With this control, the user can know chords or chord progress patterns suited for the style even if he or she does not have a sufficient knowledge about chords or chord progress patterns. In addition, the user can create chord progress data for an automatic accompaniment operation by selecting chords or chord progress patterns from the informed chords or chord progress patterns.
