Brass Instrument Mute Overview

Mutes for Brass Instruments - A Brief Review

When it comes to mutes whether you are buying your first mute or looking for that ‘special’ sound you need to know a bit before you can choose the right one for your use. Mutes are an important part of your kit and a selection of sounds and types will help you to meet your playing demands as well as increase your enjoyment. Thomas

First a bit of background for those who need help choosing.

Mute Types -

Straight – The one to buy as your first mute. It is good for all-round use and the most often specified by composers. Offers a quieter 'buzzy' sound. Used in all types of ensembles.

Cup – The second most often requested. A cup mute is darker, warmer and quieter than a straight mute. Frequently specified by composers. Used in all types of ensembles.

Extending Tube or ‘Harmon’ - also known as a ‘wha wha’ mute. This is a distinctive sound usually associated with jazz use. It consists of a mute that completely blocks the bell but which has a hole in the middle of the mute in which a moveable 'extending tube' is fitted. This tube can be positioned in different places for effect or removed altogether. If the tube is in place and the player uses their hand to cover and uncover the opening the end of the tube a 'wha wha' sound is produced. Miles Davis was a very prominent user of the Harmon mute without the extending tube.

Adjustable Cup – A ‘two for one’ value purchase. The Cup section can be removed leaving a straight mute or repositioned to work as a cup. A neat solution if a player wishes to carry around only one mute.

Practice – Very effective mute for personal practice. Significantly reduces the audible sound to all but the player and the player can benefit from the additional resistance offered to strengthen air and lips during a warm-up.

Plunger – A jazz speciality effect mute. As the name suggest this mute looks uncannily like a plumber's plunger used to unblock pipes - and indeed the original plunger mutes were just that! The mute is used to contrast an alternating closed and open sound. One can practice making an instrument 'talk' almost like speech.

Bucket Mute - Clips on the the bell and produces a distinctive sound. Primarily requested in big band swing music.

Stopping/Transposing – For the French Horn player for pitch alteration and tonal effect – mimics the effect of the ‘hand stop’ but in a mute.

Silent Practice Mute – The Yamaha Silent Brass system virtually eliminates all sound from the instrument yet retains a natural sound quality to the player via earphones. Practice anytime / anywhere with no compromise in feel. An amazing technology!

Manufacture -

The  number of firms making mutes seems to increase every year with small speciality companies introducing new products or variations on established ones. The main names in the market include Humes & Berg, Denis Wick, Tom Crown and Jo Ral each of which offers a range or mutes usually available across the entire brass instrument range.

Effects of Materials –

Most mutes are made of pressed fibreboard, metal (aluminium or copper) or wood. The effects upon the resulting muted sounds are different with each material but they all function in similar ways according to the type. Mutes made from metal tend to be brighter and feel more vibrant to the player whereas fibreboard or wood is darker sounding and more restrained or 'covered'.

Learning to Use – 

Virtually all acoustic mutes have an effect upon the overall tuning of an instrument. The use of a mute raises pitch and requires some compensation by the player, at the lips may be sufficient for some smaller instruments or by pulling tuning slides a small distance when necessary. Larger instruments will require significant tuning pull. Once experience has been gained there is usually little problem adjusting to pitch requirements though reminding oneself of the playing 'feel' of the mute may remain a challenge for a period of time.

Installation – 

Most musts are held in place by small pieces of cork. If just before placing the mute in the bell the player adds a little bit of moisture (often accomplished by exhaling with mouth over the cork or by licking) to the cork and the position the mute using a slight twisting action it is less likely to fall out of the bell. It is worth taking care of your mutes for it they do become dented or cracked it will almost certainly affect their performance. Once purchased a good mute can serve for a lifetime.

The tips and comments above are the result of many years of providing help and advice, my personal interest and study, and the teaching that I have done during my career. I have many colleagues and teachers to thank for sharing their thoughts and suggestions on this and other topics. In addition I am indebted to Woodwind & Reed, Cambridge ( www.wwr.co.uk ) where, in the course of helping customers, many of these concepts have been refined and have proven helpful.
