DW4960L Buzztube for large trombone or euphonium in silver plate

A practice aid designed to fit on a mouthpiece so as to improve buzzing by creating more resistance than practising with a mouthpiece alone.  A cleverly positioned vent hole allows high notes to be more centred in order to help build a strong high register.

INSTRUCTIONS: Before warming up on the instrument, place the mouthpiece in the Buzztube, covering the vent hole with the little finger. Practise long tones and flexibilities. For the high notes, lift the little finger, uncovering the vent hole, always maintaining a clear, well-focused tone. Buzzing like this for five minutes every day will help create a full sound and immediate response.
