• 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, m7b5, 6, m6, sus4,
aug, dim7, 7b5, 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.
