5. THE ARPEGGIATOR
5.1. What's an arpeggiator?
'Arpeggio' is a musical term that basically means '˜the notes of a chord played one after the
other'. For example, if you play a C chord and then play its component notes C, E, and G
independently, you have played an arpeggio in the key of C major.
An example of notes in a chord
The same notes as an arpeggio
And you can play those three notes in any order and still have played an arpeggio in the
key of C.
An arpeggiator, then, is a form of music technology that will take a group of notes played
simultaneously on a keyboard and turn them into an arpeggio.
