Straight mutes are by far the most widely used mutes for brass. They are cone-shaped with three narrow corks to hold them in the bell. Sound emerges from the gaps between the corks. Straight mutes generally reduce low frequencies and accentuate high, giving a more nasal, reedy sound. Aluminium straight mutes have a brighter sound than those made of softer materials like plastic, fibre or wood.
