I seem to have an easier time with it on alto, though I don't have a LOT of experience with it on either tenor or alto. I basically sing the line I'm playing at the same time in the back of my throat. I'm thinking about the line and what I would do if I were to sing it to myslef, then just belt the hell out of it. It takes a ton of air and control to keep the intonation up while doing it. I've sometimes felt faint and dizzy after really going at it for a long time. Almost makes me think I could be doing something wrong myself, but the results are in my sound. which is nice. I found this helpful: www.petethomas.co.uk/saxophone-growl.html Eric :-)
