Learn how to sing harmony and polish your harmonizing skills with this fun multi-track harmony singing app. The app comes with three songs, with many more songs available through in-app purchase. Build your harmony vocal skills by playing or muting any of the singers as you sing along with 4-part vocal arrangements of "Lean On Me", "Teach Your Children", and "Swing Low, Sweet Chariot".

The 50 additional songs available through in-app purchase include "Hallelujah", "Rolling in the Deep", "Amazing Grace", "Take it Easy", “Bridge Over Troubled Water”, “California Dreaming”, “Imagine”, and many more.


Tap ‘play’ to hear a 4-part harmony version of the song. Tap any singer to rotate through the three volume settings: full, soft, and silent. Tap the band in the background to turn the music track on or off.

To hear and learn any of the parts, mute the three other singers and sing along with the solo voice, with or without the music track. Then tap any or all of the other singers and sing your part along with them.

The voices can be added or muted as the song progresses, and can be played at half volume as a guide while the other voices are set at full volume.
