The Concerto’s headstock is an “X” shaped like the upper half of the Nobody sigil. It is mostly grey, but the tips of the X are violet. The sitar’s neck is violet and has ridged, grey edges. The body has a roughly semi-circular shape, and its base is lined by five silver spikes. The upper half of the sitar’s body is predominantly violet, and the lower half is predominantly pale yellow with two thin, violet sections on its sides. The Concerto has three white strings that are anchored to the lower half of the body. The Concerto and the Da Capo are palette swaps of each other.
Musically, a concerto is a three-part musical work in which one solo instrument is accompanied by an orchestra.
Concerto's ground combo starts with a quick leap forwards, thrusting the sitar diagonally upward, followed by Demyx performing a 360-degree spinning diagonal slash with the tip of the sitar. The next move of the combo is a quick thrust of the sitar diagonally upward, followed by another 360-degree spinning diagonal slash. The combo then ends with four quick blasts of yellow shockwaves in an outward direction.
The aerial combo consists of a series of very fast airborne spinning attacks, followed by a blast of three yellow shockwaves forwards. This weapon has no -Combo.
