At about 15, I loved the sound of the flute and had the opportunity to learn it. Problem: my lips are a mess. I have a cleft lip and palate and had had many plastic surgery procedures, most dramatically an Abbé flap, where a Y-shaped piece of my lower lip was cut out and inserted into my upper lip to fill the gap after a lump of scar tissue was removed - this meant spending 3 weeks with my lips sewn together in the middle while the blood vessels reconnected. So, I don't have those continuous horizontal lip muscles you see in muscle anatomy diagrams. Making an embouchure requires different tricks than any teacher knows about. So one motivation I had was sheer bloodymindedness. And at first I had a residual scarred lump that needed a minor plastic surgical snip to get the airflow right. I had tried the recorder before (no embouchure funnies) but didn't get to really like it until ten years later.

Other wind instruments played much the same, with reeds hitting another problem: I have a fistula in the roof of my mouth that leaks air and saliva with high intra-oral pressure (like blowing up a balloon). Another exercise in bloodymindedness. I figured out I could block the leak with sheets of denture fixative sealant, so that made the clarinet and saxophone possible (Highland pipes, no). Lost some upper teeth and the gap opened up more on one side, so I got that patched with more plastic surgery. Then after a few years more teeth started getting wobbly - after having them removed, my current denture works fine. I've been playing the sax this evening and I've still got denture fixative sheet and Fixodent sealing things up, I forget it's there.

I do play non-blowing instruments as well, but the ones that make it a fight with destiny come first.
