FAQ

Does every chart include a melody?

No. The repertoire includes complete melody pieces and clearly labelled chord-only charts. Misty and Isn't She Lovely currently include chords and voicings only.

Can I see both piano staves?

Yes. Solo view combines an available melody with the selected left-hand pattern. Accompaniment view shows the piano backing parts.
