Wii Music Orchestra will focus on Play Sessions, and gamers can choose to play among over 40 available parts (such as playing the bass guitar, trumpets, etc.). Each instrument will have its own set of controls.

As for the question of up to how many people can play at the same time - there are 40 available instrument roles to choose from, after all - up to six players can make beautiful music together: four human players, accompanied with two characters controlled by A.I.
