Hello, I just registered with this wonderful site ! But now I need some help getting up to speed. I need advice in many areas. I am
essentially a sax player who sometimes dabbles in the trumpet.
I have a basic understanding of the mechanics of the trumpet, but
I do not understand more specific details such as how a lead pipe
affects sound, and how to match mpc sizes to different bores ...

If I were to guess, a lead pipe for a trumpet affects sound much like a sax neck does. But typically , a sax neck will be standard in size
for that particular horn. And if I understand it correctly, a trumpet lead pipe can differ in length ?

I guess what I am looking for is basic information of what goes into
making sound . I know that is a loaded question, with I'm sure many
variables to compound the issue. Can anyone direct me to a source to help me better grasp the issues ?

All advice is appreciated , and thanks for having me here !
