Question

Why do French hornists keep a hand inside their bell?

In: 34

Answer 1

Several reasons:

1. Before valves were invented, the specific placement of a hand inside the bell helped the hornist play different notes not available on a natural horn.

2. Fully putting the hand in gives you a very distinct muted effect.

3. There isn’t exactly another place to hold it.
