Using the Chord Book
The Chord Book mode of this keyboard lets you use button
operations to sound a chord, even if you do not know how to
finger it on the keyboards. Specifying a chord using the Chord
Book also causes its Auto Accompaniment to play.
What is a chord?
A chord is made up of a root note, upon which is stacked a
number of other notes. A variety of different chords can be
created by changing the notes stacked onto a root.
Chord Names
Chords are named using upper-case letters from A through
G, which indicate the root note of the chord. If the root note
is a sharp or flat, the chord itself is sharp or flat. A chord
name may also be followed by a degree number or other
symbols that indicate certain characteristics about the chord.
