While the concert chord and standard 
fingering methods limit chord formations to 
the accompaniment keys, the full-range 
chord method lets you play chords of any 
type using any of the keyboard’s keys.

Set

MODE

 to 

FULL RANGE CHORD

 and 

follow the steps under “Standard Fingering”. 
If you press three or more keys that form a 
chord anywhere on the keyboard, the 
keyboard plays that chord. The keyboard 
responds with melody sounds if you press 
fewer than three keys. 

±

In the full-range chord mode, the keyboard 
recognizes 23 more chords (in addition to 
the 15 in the fingered chord mode). The 
following is an example of those chords with 
C as the base note.

Standard Fingering

•

You do not have to press the key marked 
with parentheses on the keyboard in the 
chart to produce a 7, m7, M7, mM7, add9, 
or madd9 chord.

•

Although the chart shows only one possible
fingering position for each chord, it is 
possible to play a chord using several 
different positions. For example, the 
following three positions produce the same 
C chord.

•

When you play an aug, 7

J

5

, or dim7 chord, 

the lowest note you play determines the 
root of the chord. Be sure that your 
fingering correctly defines the root you 
want.

•

See “Fingered Chord Chart” on Page 31 for
all the chords you can play on your 
keyboard using standard fingering 
accompaniment.

Full-Range Chords

•

You cannot use inverted fingerings. The 
lowest note is the root.

•

You can play the same chord without 
pressing the 5th G.

•

When the notes of a chord are more than 5
notes apart, the lowest sound becomes the
base note.
