D. Mirvil 5 Signature Bass Trombone Mouthpiece – The Closest Thing to Perfection

Designed in Collaboration with Dr. Dunwoody Mirvil While no mouthpiece can claim absolute perfection, the D. Mirvil 5 comes remarkably close — a testament to thoughtful design and real-world performance needs. Created with Dr. Dunwoody Mirvil, former member of the Tallahassee Symphony Orchestra, this signature bass trombone mouthpiece is the go-to for players who demand total versatility across the full range of the instrument.As an active performer, educator, and clinician with decades of experience (including orchestral work, jazz/R&B, and low-brass leadership), Dunwoody emphasizes mastery from the deepest pedal tones to the most brilliant upper tessitura.

The D. Mirvil 5 delivers exactly that:

• Brilliant sound in the upper register — Crystal-clear highs and secure tessitura that shine in orchestral settings, with effortless projection and focus
• Rich, euphonious low-end — Warm, resonant depth and core tone that rivals dedicated bass trombone mouthpieces — ideal for foundational support or solo passages
• Seamless versatility — Handles technical passages with ease and grace, while beautifying lyrical playing with a vocalist's touch — smooth legato, expressive dynamics, and musicality throughout
• Balanced playability — Responsive, centered, and forgiving across the entire range, making every style feel natural and confident

Stainless steel construction ensures maximum efficiency, hypoallergenic comfort, and lifetime durability — every breath transfers into vibrant, consistent tone that feels alive and effortless.

Dr. Dunwoody Mirvil's Own Words:
"While I have a clear understanding that there is no such thing as a 'perfect' mouthpiece, the 'D. Mirvil 5' is probably the closest thing to it. As an active performer and teacher who emphasizes the entire range of the trombone, the mouthpiece provides me the versatility to perform with a brilliant sound in the upper tessitura in orchestral settings, while also providing a rich and euphonious sound in the lower register, which would be expected from a bass trombonist. The mouthpiece also enables me to perform technical passages with ease and beautifies my lyrical playing with a vocalist's touch."
