Auto Accompaniment
Using Auto Accompaniment — Multi Fingering
When it is set to on (page 35), the auto accompaniment function automatically
generates bass and chord accompaniment for you to play along with, by using
Multi Fingering operation. You can change the chords of the accompaniment by
playing keys in the auto accompaniment section of the keyboard using either the
"Single Finger" or "Fingered" method. With Single Finger you can simply play a
one-, two- or three-finger chord indication (see Single Finger Chords below). The
Fingered technique is that of conventionally playing all the notes of the chord.
Whichever method you use, the PSR-280 "understands" what chord you indicate
and then automatically generates the accompaniment.

Chords that can be produced in Single Finger operation are major, minor, seventh

(The key of C is used here as an example; other keys follow the same rules. For
example, Bb7 is played as Bb and A.)
