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.
