•Notes in parentheses can be omitted.

•Playing two same root keys in the adjacent octaves produces accompaniment based only on the root.

•A perfect fifth (1 + 5) produces accompaniment based only on the root and fifth which can be used with both major and minor chords.

•The chord fingerings listed are all in “root” position, but other inversions can be used — with the following exceptions:

m7, m7b5, 6, m6, sus4, aug, dim7, 7b5, 6(9), 1+2+5.

•Inversion of the 7sus4 and m7(11) chords are not recognized if the notes shown in parentheses are omitted.

•The AUTO ACCOMPANI- MENT will sometimes not change when related chords are played in sequence (e.g. some minor chords followed by the minor seventh).

•Two-note fingerings will produce a chord based on the previously played chord.
