Past Participle: arpeggiated
Arpeggiate → It is formed from "arpeggio" (from Italian *arpeggiare*, meaning to play on a harp) and the suffix "-ate" (meaning to make or to perform). The word "arpeggiate" means to perform a musical passage in the style of an arpeggio, which involves playing the notes of a chord in succession rather than simultaneously.
Imagine playing a harp, where you 'perform' ('-ate') the notes of a chord one after another, just like in an arpeggio.
