What the AI looks for in Brass Instrument Mutes

Instrument and bell size match: Buy a mute made for your exact instrument: trumpet, cornet, flugelhorn, horn, tenor or bass trombone. Tenor and bass trombone mutes are not interchangeable. A mute that is too small falls into the bell, and one that is too large never seats. Either way the intonation and sound are off.
Mute type for the music: Most charts call for a straight mute first, then a cup mute, then a Harmon (wah-wah) or plunger. Practice and silent mutes are a separate category. The part tells you which mute is required, so you cannot substitute one type for another.
Material: Aluminum is bright and projecting. Copper-bottomed aluminum is slightly darker. Fiber or stonelined cardboard is darker and quieter. Wood and fiberglass are specialist choices. Material sets the timbre more than brand does. Section players should match each other.
Cork fit and intonation: Corks must hold the mute firmly without sealing the bell. If the instrument goes sharp or stuffy with the mute in, the corks are usually the problem. Most mutes push pitch sharp. Cork thickness and placement decide how much, and whether low notes still speak.
Practice mute back pressure: A practice mute should cut volume while still letting low and high registers slot. Heavy back pressure is a warning sign. Fighting resistance for long sessions can build bad habits that show up when you play open.

Unbranded plastic mutes that are the wrong size or have hard, thin corks.
Using a straight mute where a cup or Harmon mute is called for.
Practice mutes so resistant you cannot play softly or in the low register.
Buying a section mute without checking what material the rest of the section uses.

Usually yes. Cornet and especially flugelhorn bells differ from trumpet bells, so buy mutes labelled for them.

Most straight mutes raise pitch a little. Adjust your tuning slide, or sand the corks slightly so the mute sits a little deeper. Do this gradually.
