The number of accompaniment keys
you press determines the type of chord
that plays. The following table shows
the type of chord that plays when you
press one, two, three, or four accom-
paniment keys at the same time.
The lowest note you play determines
the key of the chord. For example, if
the lowest note is C, the keyboard
plays a C chord.
Note: You can press any labeled
note(s) to the right of the lowest note in
the chord to produce a minor, a domi-
nant seventh, or minor seventh chord.
