Muirhead-Wallace M17 cornet/trumpet practice mute

The Muirhead-Wallace M17 B-flat/C trumpet/cornet studio practice mute features a unique adjustable resistance system, allowing players to tailor airflow and feel. Despite its lightweight design, it offers exceptional intonation and response, making practice natural and effective.

Perfectly in tune and very free-blowing, the M17 doubles as a quiet straight mute, combining versatility with precision engineering for serious players.

Practice mutes have a similar conical design to straight mutes but with a solid cork bell seal to block off the sound. Air flow is greatly reduced and escapes almost silently through a small hole in the body of the mute. They are used for warming up and practising without disturbing the peace.
