In music, an arpeggio (plural arpeggi or arpeggios) is Italian for broken chord where the notes are played or sung in sequence, one after the other, rather than ringing out simultaneously. This word comes from the Italian word "arpeggiare" , which means "to play on a harp". Formed from scales, the arpeggio is based on the relative scale playing the "key" notes or those affected by the key signature.
