Chantlings

This app is not traditionally very accessible, but I thought it worth putting here because you can tap on the screen to add/remove voices. If you wear headphones, you will hear where the Chantlings are in your stereo field. Tapping on the screen on the bottom left/right and top left/right will start the various voices singing. I also think you can slide your fingers up and down to raise and lower the notes they sing, although this is less exact and I'm not sure how to do it consistently.
