Wobble board

The wobble board is an instrument popularized by Rolf Harris and is featured in his song "Tie My Kangaroo Down, Sport". Wobble boards, like other instruments such as guitars and so forth can be ornately designed due to it's inherent large surface area acting as a canvas and not detracting from its musical capability.

Rolf's instrument was originally made from a special type of plywood known as hardboard. It is played by holding the board lengthwise, hands at the sides and flicking the board outward, making the characteristic "whoop-whoop" noise. This sound is slightly comparable to the sound of flicking a turntable. The angle the board is held at and the way the board is 'flicked' can alter the timbre of the wobble board.
