Abstract: An automatic accompaniment generating apparatus capable of generating automatic accompaniment as intended by a user. In an arpeggio sounding data generation mode, when key depression tones are input by a user's key depression operation after arpeggio pattern data is selected and a loop count is set to a value of “1” by the user, the sounding of the key depression tones is started, and the generation of a sounding data list is started based on the tone pitches of the key depression tones and sounding pattern data included in the selected arpeggio pattern data. In the case of the loop count being set to “1”, the reproduction of the sounding data list is completed at the end of one bar, and thereafter only the key depression tones are sounded until a key release operation is performed by the user.
