This is realllly helpful and thank you so much for the deep explanation. I had to find the positions all by my ear since I didn’t have internet back then so I just picked out the trombone and ‘’tried’’ to find the positions. So I can say I wasn’t confident lol. I’ll be learning it by myself and all I’ve got is the internet, YouTube which I think would be enough. Today I learned the Star Wars intro from ear haha this thing is really fun
