Brass instruments

Annotations:

• These are made with metal. The tube of the instrument is folded or coiled around itself to make it more functional. The pitch of the sound depends on the air pressure the musician produces on the mouthpiece and a system of valves and pistons. 

1. Trombone

   Annotations:

   • Instead of pistons, the trombone uses a moving slide. 
2. French horn
3. Tuba
4. Trumpet
