Interesting sounds can be created using a variety of sources if you have a looping pedal and pitch shifting ability. Richie Brown made a maraca out of a mannequin leg, currently for sale on eBay, and his video demonstrates just that. The leg is basically a shaker filled with various small objects and a piezo disk mic to turn the acoustic sounds into an electrical signal.
Richie’s past and future projects include more mannequin recasings with conveniently placed touch contacts.
Touch Me – a public installation encourages spectators to interact with letters on a board by rubbing, poking, scratching, caressing, and knocking. These noises are picked up by the contact mics and fed into a looper as the day progressed.
The Monster Box demonstrated below was made out of a Roll-Up Piano Keyboard.
And the Walking Song was recorded with contact mics taped to inner thighs and inner elbows in hopes of being able to record a walking pattern. The song can is called HG Welles Walks and can be heard on his myspace page. Nice work, cool ideas!
