Which Denis Wick mouthpiece should I buy for my brass instrument?

Start with the instrument you play rather than the finish or artist name. The Denis Wick Maurice Murphy MM4C Silver Plated is a trumpet mouthpiece; the Steven Mead SM6 Gold Plated is for baritone; and the Classic 4 Silver Plated is for tenor horn.

The supplied details don’t include cup dimensions, rim profiles or shank measurements, so they aren’t enough to judge which will suit your embouchure or confirm the fit with your particular instrument. Check those specifications before ordering.

If possible, try the appropriate model against your current mouthpiece. Listen for a consistent tone and check comfort and response across your usual range—gold plating alone isn’t a reason to expect a better match.
