An arpeggio is a group of notes played one after the other, up or down in pitch. The player plays the notes of a particular chord individually rather than together. The chord may, for example, be a simple chord with the 1st, (major or minor) 3rd, and 5th scale degrees (this is called a "tonic triad"). An arpeggio for the chord of C major going up two octaves would be the notes (C, E, G, C, E, G, C). An arpeggio is a type of broken chord. Other types of broken chords play chord notes out of sequence or more than one note but less than the full chord simultaneously.
