Using Auto Accompaniment
With Auto Accompaniment, simply select an accompaniment 
pattern. Each time you play a chord with your left hand the 
appropriate accompaniment will play automatically. It’s like 
having a personal backup group along with you wherever you 
go.
 Auto Accompaniments are made up of the following three 
parts.
(1) Rhythm
(2) Bass
(3) Harmony
You can have only the rhythm part play, or you can have all 
three parts play at the same time.
The rhythm part is the foundation each Auto Accompaniment. 
Your Digital Keyboard comes with a variety of built-in rhythms, 
including 8-beat and waltz. Use the following procedure to 
play the basic rhythm part.
1.Press bq.
2.Use bo (10-key) to select the rhythm number 
you want.
 See the separate “Appendix” for information about 
individual rhythms.
 You also can find out rhythm numbers using the rhythm 
groups printed on the Digital Keyboard’s console.
3.Press bl or 8.
This starts the rhythm.
4.Play along with the rhythm.
5.To stop the rhythm, press bl again.
