I've taken apart a couple of discarded pianos. The saddest part is cutting the wires with a wire cutter (watch it, they whip outward) - the sound is so mournful and haunting.

"The discordion."
Do you know the sound that the TARDIS makes when it materializes? Part of that sound is someone at the BBC radiophonic workshop scraping a wrench against the strings on a harp from a disassembled piano.
