Well, as an admirer of Roland Kirk I'd certainly be interested in a stritch (straight alto) or a manzello, but generally I'd like the big buggers - soprano is as high as I want to go really, but I'd love a go on a bari or bass sax, or even lower, the contra-mega-how-low-can-you-go sax known as the tubax. Now that is basso profundo.
So, a quick poll - soprano sax, straight or curved? After about 3 hours playing it yesterday, my vote goes to my curved soprano over the straight one. She's so cute!
Cheers, Bob
