Arpeggio

Arpeggio (アルペジオ) is a weapon that can be used by Demyx in Kingdom Hearts 358/2 Days. In Kingdom Hearts II, the Arpeggio is his only weapon.

Design
The Arpeggio is designed to resemble one large Nobody logo. The headstock of the sitar consists of three large, light blue spikes with blue bases. The neck of the sitar is blue with light blue, concave edges, and three yellow, pointed machine heads are visible on the left side of the weapon. Several yellow frets line the fretboard. The body of the Arpeggio is connected to the neck by a dull blue spike shaped like those on the Nobody logo, and the body itself is shaped like the lower half of the symbol. The shape of the symbol (in particular, the two circular indentations on the sides) is distinguished from the rest of the sitar by a light blue border. The sitar's saddle is yellow and its three strings are a very pale blue.

Etymology
Musically, an arpeggio is the playing of notes from a single chord in rapid succession.
