The 18 keys on the left side of the keyboard 
with note labels above them are called 
accompaniment keys. 
You can set the keyboard to play three 
different types of auto accompaniment using 
the accompaniment keys. 
±
• Concert Chord — lets you play chords
on the accompaniment keys using 
chord formations of from one to four 
notes. The number of keys you press 
determines the type of chord that plays 
(see “Concert Chord”).
• Standard Fingering — lets you play
chords on the accompaniment keys 
using standard chord formations of 
three or four notes (see “Standard 
Fingering” on Page 11).
• Full-Range Chord — lets you play the
melody using the entire keyboard while 
the keyboard plays accompaniment 
based on your auto-rhythm selection. 
The auto-accompaniment patterns consist of 
four parts: chord 1, chord 2, bass, and 
rhythm. You can delete any of the parts by 
using the mixer function. See “Using the 
Mixer” on Page 12.
