There was a young man from Portland (no this isn't a limerick) who became quite well known for his ability to play a rubber band using it as a reed instrument. He stretched it and blew through two pieces of a flat rubber band to produce musical tones. He even headlined his own electric rock band as a soloist on this most unusual instrument. This works similar to how the stretched opening of an inflated balloon can create musical tones. Or, reaching further back into obscurity, how people managed to play the tire pump by squeezing the hose together while pumping to create exact tones. I guess now that I've got that saw thing down I'll be lookin' for new frontiers to conquer. The tire pump may be just the ticket. Anyway it certainly could come in handy considerin' how often I sing notes flat.
