Casio Chord system
The Casio Chord system has been developed so you
can play the four main types of chords more easily.
Playing of the chords is simplified as shown below:
¢ Pressing one of the accompaniment keyboard keys
produces a major chord corresponding to that
note.
¢ Simultaneously pressing any key to the right (two
keys at the same time) results in a minor chord.
¢ Similarly, pressing one more key to the right (three
keys in all) produces a seventh chord, and press-
ing the fourth key to the right (four keys in all)
creates a minor seventh chord.
< Examples >
C (C major chord)—Press @.
Cm (C minor chord)—Press @, @ together.
C7 (C seventh chord)—Press @, @, © together.
Cm7 (C minor seventh chord)—Press @, @, ©, ©
together. clole ir|olaleiciole le
