An auto-play electronic musical instrument stores note data of phrase tones for one bar corresponding to each of a plurality of keys of two octaves together with auto-accompaniment pattern data. Every time a key is operated, an adlib play is made by playing back corresponding phrase tones. When a key operation is interrupted during the adlib play, specific phrase tone are repetitively and automatically played back, thereby preventing a play from being interrupted halfway. The electronic musical instrument also stores fixed phrases such as introduction, fill-in, ending phrases, and the like, which are required according to the flow of a play. When one of the fixed phrases is played back by a selection button while the specific phrase is repetitively played back, the repetitive playback operation of the specific phrase is restarted when the playback operation of the fixed phrase ends. As a result, a user can play similar to a professional artist even with one finger in this key-on phrase play mode.
