About BrassFitMouthpieces.com

BrassFitMouthpieces.com is the most comprehensive brass mouthpiece comparison site on the web — covering 1,000+ mouthpieces from 70+ brands with full specs: rim diameter, cup depth, throat size, backbore, shank type, and more.

Unlike scattered forum posts and manufacturer pages, every mouthpiece here is standardised with comparable measurements. We cover trumpet, trombone, French horn, tuba, and euphonium mouthpieces — from current production models to vintage discontinued pieces.

Who maintains this site?

This database is maintained by a doctoral researcher specializing in brass embouchure injuries and performance science. My research examines how mouthpiece design, instrument setup, and playing technique interact to affect brass musician health and performance longevity.

That expertise means the data here reflects real understanding of what each spec means for playing — cup depth affects tone colour and endurance, rim contour affects comfort and flexibility, and throat size affects resistance and volume.

How is the data collected?

• Manufacturer catalogues — official specs from brand websites and printed catalogues
• Physical measurements — verified specs from actual mouthpieces
• Community contributions — especially for vintage and discontinued models via our Vintage Archive
• User submissions — players and dealers can submit additions or corrections
