SchilkeSymphony M Series Trombone Mouthpiece in Gold
Independent shopping perspective
The Korena take
Gold-plated Schilke Symphony M trombone mouthpiece in four models: three medium-shallow K-throat sizes and one deep O-throat. For players who already know their rim size.
Strong match
Who this is for
- Lead and commercial playing where projection matters more than a dark core
- Orchestral volume on the M6.0's deep cup and open throat
- Stepping rim diameter up in small increments through 5.1, 5.2, 5.3
Consider the trade-offs
When to look elsewhere
- Players who don't yet know their rim diameter
- A dark, covered sound — the K-throat cups run bright
- Anyone wanting one mouthpiece that covers everything
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
O throat, deep cup (M6.0)
More air moves through and the tone stays broad. Upper register asks for more support in return.
Detail 03
Rim grows from 5.1 to 5.2 to 5.3
Same cup character throughout. Bigger rims give low notes room; smaller rims concentrate pressure and help endurance.
Detail 04
Large Schmidt backbore on the M6.0
Opens the passage past the throat. Blowing feels freer and the tone holds together at high volume.
Detail 05
M6.0 keeps the 60 rim with a 59-style cup
Deeper cup on a rim size you already play. You change depth without relearning how the rim feels.
Detail 06
Gold plating
A surface finish over the same cup, throat and backbore. Choose it for feel on the lip.
Final check
Know before you order
- 01One model per order — confirm you are buying 5.1, 5.2, 5.3 or 6.0
- 02Mouthpiece only. No pouch, case or cleaning brush
- 03Changing cup depth shifts intonation; expect to reset tuning and slide positions
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the difference between the 5.1, 5.2 and 5.3?
The cup is the same on all three — medium shallow with a K throat. Rim diameter is what changes: 5.2 is wider than 5.1, and 5.3 wider again.
02Which model is the orchestral one?
The M6.0. Deep cup, open O throat and a large Schmidt backbore, on the rim diameter of a 60. It stays even and has volume in reserve.
03Does the gold change the sound?
The playing characteristics come from the model number — cup depth, throat and backbore. The plating is the surface you feel on your lip.
04Will a shallower cup give me high notes?
The K-throat models add brilliance and projection and make the top of the range easier to place. They don't replace air support or practice.
