• Notes in parentheses can be omitted.
•Playing two same root keys in the adjacent octaves produces accompa-
niment 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, m7
b
5, 6, m6, sus4,
aug, dim7, 7
b
5, 6(9), 1+2+5.
NOTE
•Inversion of the 7sus4 and m7(11) chords are not recognized if the
notes shown in parentheses are omitted.
• The auto accompaniment 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.
