Since the 1930s this instrument is known simply as the “Horn” in some professional music circles.
It’s a brass instrument made of tubing wrapped into a coil with a flared bell. It’s also a brass instrument with the widest note range. The most noble sounding of the brass instruments in classical music is the French Horn with a full rock tone.
Its an accompanying instrument and at the same time improvises in jazz music. To learn this instrument, one requires ability to practice.
French Horn students at the IMLS also play in the Brass Band. Thereby they learn to play music together and how to work on a piece in a group.
