CON SORDINO (MUTE TO BE USED):
This indicates that the mute, in the form of a cone or pear-shaped stopper, is to be placed inside the bell of the instrument. This is to muffle the volume and brightness of the brass tone, making the sound quieter and more subdued, as if the sound were coming from afar.

CLARINO PLAYING:
This was developed in the 18th century as a valveless trumpet used in medieval times that could only play the notes of one harmonics series at a time. As it is very difficult to play very high harmonics on the trumpet, Clarino players require a lot of skill in lip control and breath pressure.

CUIVRE:
Indicated with a + sign over the note, this applies to the horn only. It signals that the note is to be produced with the player's hand pushed all the way inside the bell, forcing the sound out. This results in a very brassy and noisy sound.

PAVILLON EN L'AIR (BELL IN THE AIR):
The bell of the instrument is to be raised up high, making the sound more prominent.

GLISSANDO:
Applying only to the trombone, this indicates that the player is to pull the slide in or out, while blowing continuously into the tube.

STOPPED NOTES: Indicated with a small circle over the note, this applies to the horn only. It indicates that the note is to be produced with the player's hand inside the bell. This is usually used for producing certain notes which cannot be achieved by pressing on the valves. These notes are distinctively different in terms of tone quality.
