A karaoke apparatus is constructed for playing a karaoke song according to song data jointly with a first vocal part and a second vocal part. In the karaoke apparatus, a generator device processes the song data to produce an orchestral accompaniment sound during the course of play of the karaoke song. A first input device collects a first singing voice which is physically sung along the orchestral accompaniment sound to fit with the first vocal part. A second input device collects a second singing voice which is physically sung along the orchestral accompaniment sound to support the first singing voice. An adjuster device adjusts at least a pitch of the second singing voice collected by the second input device according to reference data contained in the song data so as to fit the second singing voice with the second vocal part. A mixer device mixes the first singing voice collected by the first input device and the second singing voice fed from the adjuster device together with the orchestral accompaniment sound to thereby effect play of the karaoke song. The first singing voice may be of a main melody, while the second singing voice may be of a harmony melody or a back chorus.
