I once watched my friend learn to play the saxophone, and we spent a good long while in giggles while he made pretty much fart noises while he figured out his embouchure (it's what you do with your lips and things to make a note with the reed + the mouth piece). Because of that singular, incredibly amusing experience, I thought it was difficult. Turns out it's not really difficult at all. My friend Cee had a sax, and when I told her I'd added this to The List, she offered to teach me. An hour or two later (with only a few random fart noises) I was making many clear notes. Fun times!
I didn't expect it be that easy, so this was taken on my phone. It's a bit shit, but perfectly demonstrates that woo, #122 - done!
