Abstract
A musical accompaniment playing apparatus comprises a MIDI sound source, a phoneme information memory, a playing information memory, a control means, a mixing means and a sound output means. When a user sings a song with a musical accompaniment and a back chorus, the control means controls the MIDI sound source to output an audio signal in accordance with a phoneme information stored in the phoneme memory and a playing information stored in the playing information memory. The output audio signal is mixed with a singing voice of the user at the mixing means and output from the sound output means as a song in harmony with the back chorus.
