USING AUTO
ACCOMPANIMENT
After you select an auto-rhythm, the
Concertmate 690 lets you automatical-
ly add a harmonic accompaniment.
You can select from two auto
accompaniment types— easy random
fingering or standard fingering. Both
methods are explained in detail in the
following sections. But, in brief, to add
an auto accompaniment pattern, first
set
MODE to CONCERT CHORD for
easy random fingering or to FINGERED
for standard fingering. Then use the
“accompaniment keys” (the 18 keys
with raised labels above them) to se-
lect the chord. Use the rest of the keys
to play the melody.

Easy Random Fingering
The easy random fingering method
lets beginning keyboard players easily
select and play a chord.
The number of accompaniment keys
you press determines the type of chord
played. The following chart shows the
type of chord that plays when you
press one, two, three, or four accom-
paniment keys at the same time.
The lowest note you play determines
the key of the chord. For example, if
the lowest note is C, the Concertmate
690 plays a C chord.
