6. A Gong

Add a taste of the Far East to your jam sessions, with an electronic gong and stand! Everyone likes to hit large piece of metal with a hammer, but we admit that there's not an awful lot of scope for fitting this action into a fast paced rhythm game. Therefore, to get the most out of this peripheral, Harmonix should add a whole load of new mini-games to Rock Band 3. These could include a game where you summon people to dinner, and a challenge where you judge a Britain's Got Talent-style competition. You could also use the gong to add a ceremonial edge to beat-em-up competitions, or, if your house regularly receives royal visitors, it could be used to announce the arrival of a King.

5. A Rainstick

An ever-popular instrument with the hippie crowd, the South American Rainstick could bring the Rock Band series closer to nature. The real thing consists of a long and hollow tube filled with tiny beans; when you tip the stick upside down, the pellets fall to the other end, creating a unique noise. Of course, modern technology means we no longer have to rely on beans to recreate the sound of rain. Our Rock Band rainstick would use the world's most technically advanced sound cards, carefully smashed into tiny pieces and sealed inside an old wooden tube. The stick could be used to play along to The Doors' classic, Riders On The Storm - and to any other rain-based tunes that might exist (we couldn't think of any).
