Appcompanist gives classical and musical theater singers and voice teachers full control over the world’s best piano accompaniment recordings, including tempo, key, melody help, fermata and more.

Appcompanist puts a level of control in your hand never before possible with recorded accompaniments. Transpose to any key; set any tempo; blend a melody guide track in and out in various octaves as piece plays; create additional rubato, fermatas of any length, ritardandos and accelerandos; set markers and create cuts and loop sections, all using simple on-screen motions that can be done with one hand while teaching or singing, and all without affecting musical quality. You can even save your tempo changes and fermatti to create custom versions that play exactly the way you want every time, but still respond to any changes you decide to make on the fly!

Appcompanist also includes over 850 Vocal Exercises and Warm-ups as part of the free version, all with full app functionality. Repeating exercises also let you choose direction (up, down, or repeat the same key) prior to each repeat. 10 full-length sample songs are also included so you can explore all of the app’s unique playback features.

Top-level collaborative pianists from around the world are recording high quality, singer-sensitive accompaniments for every aria, art song, and musical theater piece in the vocal repertoire for use in Appcompanist. Thousands of titles are already available in the fastest growing accompaniment library available.

Features:

Transpose instantly up or down 11 half-steps from the originally recorded key with no change in audio quality.

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.

Hold and sustain the accompaniment, then bring it back in with perfect accuracy for musical pauses, cadenzas, recitatives, or other times in which a fermata is indicated. The fermata button can also be used to start playback at any point in the piece precisely when you're ready.

Check next melody pitch when stopped and start in perfect sync with the accompaniment every time.

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

Add markers, create cuts, and set loop sections anywhere in any piece.
