Practicing jazz improvisation is not always easy. Tritone Jazz can give you piano, bass and drums accompaniments. All you need is to type in the chords.
Melody is also played if included. Even voice, too.
The song data is actually text-format so that you can send it by text message or e-mail.
You can print the chart with chords, notes and lyrics.
