For all you head banging science nerds, the chemical composition of an electric guitar from Compound Interest (click to enlarge):
I don’t mean to get all science geek here, but we’re missing a major chemical compound in this chart: the wood that makes up the neck and the body. I don’t know what specific wood is used here (it varies by guitar), but Wikipedia tells me the main components of wood are approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements (mainly calcium, potassium, sodium, magnesium, iron, and manganese).
“It’s the Chemicals,” man! (Here’s some Inspired Flight, along with some electric guitar.)
