arpeggio
Italian universal
Definition
A chord played with notes sounded in rapid succession rather than simultaneously, usually from bottom to top.
Interpretive Guidance
Indicated by a wavy vertical line beside the chord. Speed and direction (always bottom-to-top unless an arrow indicates otherwise) should suit the style and the tempo. In Romantic music, harp-like arpeggiation is common; in Baroque keyboard writing, arpeggiation is a standard ornamental resource.
