Manufacturer’s description:
‘Made of high quality hand-spun aluminum, the Jo-Ral non-transposing straight mute has been tested to perform evenly in all registers. The mute also features neoprene-enhanced composite cork pads that grip well and don’t dry out, become brittle or break off, and so last longer while easily accommodating fine adjustments for a perfect fit.’
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.
