SINGLE FINGER accompaniment makes it simple to
produce beautifully orchestrated accompaniment using
major, seventh, minor and minor-seventh chords by press­
ing a minimum number of keys in the left-hand section of
the keyboard. The accompaniment produced is perfectly
matched to the currently selected accompaniment style.
If you press a “C” key in the left-hand section of the
keyboard, for example, a C-maJor accompaniment will be
played. Press another key in the left-hand section of the
keyboard to select a new chord. The key you press will
always determine the “root” of the chord played (i.e. “C”
for a C chord).

I For a minor chord, press the root key and a black key to
its left.
I For a seventh chord, press the root key and a white key
to its left.

a white and black key to its left.
The automatic accompaniment will continue playing even if you
lift your fingers from the Auto Accompaniment keys. You only
need to press the Auto Accompaniment keys when changing
chords.
If the SINGLE FINGER mode is used while the accompaniment
is stopped, the appropriate bass and chord sound will be pro­
duced when any left-hand keys are pressed. The bass voice is
the same as the accompaniment bass voice. The chord voice
can be selected using the VOICE SELECT buttons after a key in
the left-hand section of the keyboard has been pressed.
REVERB DEPTH (PSR-500 only), VOLUME, OCTAVE, and
PAN settings will affect the chord voice, but the DUAL VOICE
mode cannot be used.
THE FINGERED MODE
The FINGERED mode is ideal if you already know
how to play chords on a keyboard, since it allows you to
supply your own chords for the Auto Accompaniment
feature.

Minor sixth chords will only be properly detected if
they are played in “root position.” Seventh flatted fifth
chords will be recognized as long as either the root or ^
flatted seventh is the lowest note. For diminished and
augmented chords, the lowest key pressed is assumed to
be the root.

the keyboard, that note will be taken as the root and the accom­
paniment will use only that note, tf you play the root and fifth the
accompaniment will use only the root and fifth.
If you play three adjacent keys at once (semitone intervals). All
accompaniment parts except for rhythm will be muted.

hand chord is detected, and the chord will sound as played. The
chord voice can be selected using the VOICE SELECT buttons
after a key in the left-hand section of the keyboard has been
pressed. REVERB DEPTH (PSR-500 only). VOLUME, OC­
