An arpeggio is a type of broken chord in which the notes that compose a chord are individually sounded in a progressive rising or descending order. Arpeggios on keyboard instruments may be called rolled chords.

Arpeggios may include all notes of a scale or a partial set of notes from a scale, but must contain notes of at least three pitches (two-pitch sequences are known as trills). Arpeggios may sound notes within a single octave or span multiple octaves, and the notes may be sustained and overlap or be heard separately.

Quotes about the arpeggio

edit
  • More than 40 years after the release of Van Halen, the opening riff in “Ain’t Talkin’ ’Bout Love” - an arpeggiated Am-F-G5 passage played with palm-muted downstrokes - is still a favorite among beginning and intermediate pickers.
  • In the ’80s, Peter Buck’s clean, chime-y arpeggios defined the sound of alt-rock to come.
