Band size and composition will follow a general line up to include the following; 1 vocalist, 2 guitarists, 1 bassist, 1 keyboard player, and 1 drummer.
Though this is not always possible, bands will never include less than 3 members (i.e. guitar/vocals, bass, drums) or more than 7 members.
This is to allow maximum playing time and attention for each student while also staying true to a group experience in music-making.
