Recently I've been trying to get my alto playing up to scratch but am *really* struggling. I play baritone as my main instrument and concentrate on a Harry Carney-like tone on my Conn 12M with a Woodwind Co B4* large-chambered mouthpiece.
I have quite a few Conn altos (all 1930s) and one Buescher Aristocrat (1945) with a variety of old mouthpieces including a Tonalin, a couple of Woodwind Cos, a Buffet, a Conn Eagle and Steelay, Meyer 5M and 6M and other odd bits. The Conns and the Woodwind Cos have large chambers and very close tips, and so far I haven't managed to produce a decent sound with them. I have experimented more with the other pieces, and I've got a variety of different chambers shapes and sizes amongst them as you can probably guess from the list
On the altos, however, I simply can't develop an embouchure that I can play in tune with any of the mouthpieces. I'm looking for a vintage tone (Otto Hardwick, Hodges, etc), not a modern tone. On any of the "sensible" mouthpieces I simply can't get the upper register not to be sharp, whereas trying either the Conns or the Woodwind Co pieces results in an excessive swing in the other direction - upper register flat to the extreme. I can't seem to find a compromise anywhere. I'm finding this very frustrating. I can play my tenor (Conn 208xxx) fairly well in tune: the pitch seems pretty stable and centred.
I don't know how to tackle this problem. Any advice on how I should develop an alto embouchure from scratch?
