Trumpet straight mutes: The most commonly used type of mute is the straight mute, this is the default mute for orchestral playing. The straight mute was originally a hollow, cone-shaped mute that fits into the bell of the instrument although most modern mutes have a more bulbous shape. Use of this type of mute results in a more metallic, sometimes nasal sound, and when played at loud volumes can result in a very piercing tone.

Metal mutes are generally ideal for loud passages (aluminium produces the most lively and vibrant sound with copper sounding fuller/darker, brass somewhere in-between) while softer passages can often be executed more effectively using a fibre or wooden mute (look at Denis Wick. Humes & Berg and Proline for these). Straight mutes are available for all brass instruments, from piccolo trumpet to tuba.

Other types of mutes include practice, cup, harmon/wah-wah/ET (all the same thing!), bucket and plunger.
