Using Auto Accompaniment
• If you play any three adjacent
keys (including black keys), the
chord sound will be canceled and
only the rhythm instruments will
continue playing (CHORD CAN-
CEL function).
• An octave produces accompani-
ment based only on the root.
• The chord fingerings listed are all
in “root” position, but other inver-
sions can be used — with the
following exceptions:
* 6 chords are only recognized
in root position. All other inver-
sions are interpreted as m7.
* m6 chords are only recognized
in root position. All other inver-
sions are interpreted as m7
b 5.
* 1+2+5 chords are only recog-
nized in root position. All other
inversions are interpreted as
sus4.
* With augmented chords the
lowest note played is assumed
to be the root.
* With 7 b 5 chords the lowest
note played is assumed to be
the root or
b 7.
● NORMAL
This is the default FINGERED accompaniment mode. The NORMAL
mode lets you finger your own chords on the left-hand section of the
keyboard (i.e. all keys to the left of and including the split-point key —
normally 54 while the PSR-320/420 supplies appropriately orchestrated
rhythm, bass, and chord accompaniment in the selected style.

parentheses may be omitted).

● FULL
In this mode chords played anywhere on the keyboard are detected and
used for Auto Accompaniment. Otherwise the keyboard functions nor-
mally, and the entire range is available for playing. Chord recognition is
the same as in the NORMAL mode. This means you can play in just
about any style anywhere on the keyboard, and the PSR-320/420 will
automatically produce appropriate accompaniment.
• A single note eleven notes higher
than the lowest note of the chord
is recognized as a melody note.
• The Harmony function (page 31)
has no effect in the FULL mode.
