Finally - a chord-book for keyboard! So far now only available for guitarists & co. - now a practical format to bring everywhere (fits every softbag/case) now for keyboard-player.

Chords are sorted by tonality, each keyhas its own colour - makes it easier to find. Followed by parallel-keys, meaning A-Minor after C-Major, E-Minor after G-Major, B-Minor after D-Major, F#-Minor after A-Major etc. In addition there are keys sorted by type of harmony- augmented, diminished and half-diminished
