According to a Selmer catalogue from around 1975, the information I gave is correct. Also, if you look at a Woodwind/Brasswind catalogue mouthpiece chart, you will see that the * sizes and non * sizes are the same opening. With most other mouthpieces the * indicate a larger tip opening.MM said:I was told that the * for the Brilharts meant a more open chamber by my teacher at the time. The first tenor mpc I owned was a Brilhart 5*.
But yeah in general it fills in the cap. Selmer's mouthpieces go ...C,C*,C**,D,E etc. in order of tip opening.
