● Example for “C” chords
• Notes in parentheses can be
omitted.
• If you play any three adjacent
keys (including black keys), the
chord sound will be canceled
and only the rhythm instru-
ments will continue playing
(Chord Cancel function).
• Playing a single key or two
same root keys in the adjacent
octaves produces accompani-
ment 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), m7_11,
1+2+5.
• Inversion of the 7sus4 chord is
not recognized if the 5th is
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 pro-
duce a chord based on the pre-
viously played chord.
