Using screwdrivers, chisels, chainsaws and whatever other tools you might need, disassemble your instrument, deconstruct it into as many different component parts as possible.
Perform a brief cadenza on each distinct part.
To the best of your ability, re-assemble and reconstruct your instrument.
Perform a brief cadenza on the reconstructed instrument.
Switch off the power.
