Trumpet Straight Mutes

The most common type is the straight mute, a hollow, cone-shaped mute that fits into the bell of the instrument. This results in a more metallic, sometimes nasal sound, and when played at loud volumes can result in a very piercing note. Straight mutes have small pieces of cork attached to the end that squeeze against the inside of the bell and hold the mute in place. Most metal straight mutes are made of two parts crimped together. They are known for their sharper pitch. Newer mutes from Soulo Mute for example, are made without a crimped connection, which allows the air to flow freely and improving the pitch. Straight mutes are available for all brass instruments, including the tuba.
