Arpeggio

Arpeggio is an Italian musical term literally meaning like a harp. It is used to indicate that the consecutive notes of a certain chord are to be played quickly one after another, instead of at the same moment.

In piano music this is sometimes a solution used to play a wide-ranged chord which, technically speaking, cannot be played simultaneously with one hand. Music played on the limited hardware of video game computers uses a similar technique to create a chord from one tone generator.
