Arpeggio

Arpeggio is Italian musical term for like a harp. It is given by the composer to indicate that the consecutive notes of a certain chord are to be played one by one, quickly after each other, instead of at the same moment. In piano music this is sometimes a solution 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.
