Using the Chord Book

The Chord Book feature of this keyboard makes it possible

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.
<Example: C chord>
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 sym-
bols that indicate certain characteristics about the chord.

upper row of this illustration are used by this
keyboard, because they are the names that are

Inverted Forms
There are a number of different ways to play the same chord.
A form that is different from the basic form but still produces
the same chord is called an "inverted form."
