Harmon

Metal mute wrapped in cork and inserted into bell of trumpet. The mute has a stem which is normally fully inserted, but may be pulled out or removed entirely. A 'waa-waa' effect may also be achieved by using the hand to cover and uncover the stem opening.
Notated: harmon
- stem out
- remove stem
- waa-waa (+ = shut, o = open).
Note: It is best to clarify what you mean by 'stem out' with a note in the score. As with all mutes, allow time for inserting and removing, and indicate when the player is required to remove the mute at the end of a muted passage. The harmon mute makes a quiet sound!

The Orchestra: A User's Manual is a free resource and will remain so. It still receives between 8,000 and 16,000 unique visits per month from all over the world. See the testimonials. Thanks to all the donations, I have been able to create this responsive re-design. But the movies and sound clips recorded in 2004 do show their age. I would really like to re-record everything and add many more techniques, especially for solo and ensemble writing. I estimate this will cost around £30,000.
