I've been doing some reading, what is the optimal mouthpiece gap on a trumpet? I've measured mine on my trumpet, and it is around 0.125" using a Bach 5C MP.

What is common? And are specific trumpet models (ie. Bach 37) use a consistent gap through the years, or was it dependent on the person making the trumpet?

This is a good reference that shows the concept of a GAP, and how it can effect your sound.

There is significant variability in the exact dimensions of mouthpiece shanks and trumpet receivers between manufacturers, and even within samples from the same manufacturer. A very small difference in the dimension of either, as little a .001" in diameter, one can make a significant difference in gap. In general most mouthpiece - horn combinations will play well with a gap in the .125" range, but some players will prefer a different setup. It also varies for an individual player, depending on the equipment. Most manufacturers design their horns and mouthpieces for a gap in this range, except for Schilke, who aim for close to a zero gap.

Cheers,

I've seen anywhere from 2.5 to 5.5 mm.
