From the developer:
Accompanist will work out the chords to almost any tune you can sing.
* Start by pressing the record button
* Sing long clear notes in a quiet environment
* Headphones with microphone works best!
The names of the chords are displayed so you can copy them down for your own arrangements.
Accompanist is based upon Tonalis. Check out http://www.zilibowitzproductions.
