Jackie McLean "squeals"?
I'm wondering if any of you could tell me more about Jackie McLean's incredible "squeals", for instance here at 2:12 & 2:20 & 6:06
How does he achieve this sound? He seems to hit a concert Bb and F beyond the alto range. Is it to do with the embouchure?
I don't play sax but I'd still love to know what's going on! Thanks :)
