After 30 years of playing on a #4 reed - I went out on a limb, took Mr. Thomas' kind advice - and ordered a Selmer Soloist E mp and a softer reed (2.5) the sound is amazing....

Here's the mouthpiece math word problem (100pts) -

If an E facing with a 2.5 reed sounds amazing on a Buescher Alto, what combination might provide similar results on a 1974 Selmer Mark VII tenor (currently played with #4 reeds on a Meyer MP marked Medium with a 5 tip opening)? >:)

Well, I like a wide tip (I use 125) with softish reeds on tenor. That's a 9* which is quite big.

However I use relatively smaller tips on alto. (6 or 7) and still fine with 2.5 reeds.

Mouthpiece opening in *s is proportional to the sqaure of the volume.

So remembering that the sax is a cone (approx), derive a formula expressing the volume in terms of length, approximating pi as 22/7 if you wish. Include a factor c to account for mouthpiece chamber size and t to account for tone hole volume.

f(l) = v

integrate with respect to l (derive your own limits) and multiply the alto tip opening by Vtenor/Valto To obtain the desired result. Reduce reed strength by 0.5 for each star increase in tip opening. As you're aware reed strength can also be expressed as a second order differential of l, for values where sinl = tanl

Hi Lulu

Thanks for your reply in your previous thread I'm glad you've sorted your mpc problem.Shortly after posting to you my reed decided to give up the ghost so I set about sorting out another.I tried dozens couldn't get one to work then thinking of your mpc problem I remembered a 4c I had ,so I rooted it out it had a vandoren 3 in it I put it on the sax and I couldn't believe it was better than anything else I had tried I changed the 3 for a rico 2.5 and low and behold in the words of Hamster Hammond I am a Saxophone God or maybe not but the difference was amazing.The 4c is incredible.(Hamster may take a bit of explaining )...John:thankyou:
