    Appcompanist is designed with the singer and voice teacher in mind. Everything you need to control can be done with one hand using your touch screen.


  • Transpose

    Transpose instantly and flawlessly up or down 11 half-steps from the originally recorded key.

  • Learn the Melody

    Turn a melody guide track on or off any time during play, adjust the level of melody you hear against the full accompaniment, and choose to hear melody in one of three octaves.

  • Control the Tempo

    Adjust tempo during play to suit any interpretation or set a new tempo with the tempo slider.
