Auto Accompaniment
Using Auto Accompaniment—Multi Fingering
When it is set to on (page 47), the auto accompaniment function automatically gener-
ates 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 key range using either the "Single Finger" or "Fingered"
method. With Single Finger you can simply play a one-, two- or three-finger chord indi-
cation (see "Single Finger Chords" below). The Fingered technique is that of
conventionally playing all the notes of the chord.
Whichever method you use, the EZ-20 "understands" what chord you indicate and then
automatically generates the accompaniment.

Single Finger Chords

Chords that can be produced in Single Finger operation are major, minor, seventh and
minor seventh. The illustration shows how to produce the four chord types. (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.)
