Answer:
true
Explanation:
First, we need to define a French Horn:
A brass instrument, that requires deep breath in order to produce sound. The French Horn measures around 12-13 feet long.
In case of the double Horn, there are two sets of tubing.
A F tube and a shortr Bb tube with additional rotor valves that divert air flow along the two tubes makes this instrument harder to play.
Having both horn mechanisms enables the playing of higher and lower pitch notes. In total the double French horn can play 4 octaves.
The Double Horn is an instrument usually present in an Orchestra
There are anywhere from 2 to 8 French horns in an orchestra, and half or less can be a double horn which can interpret melody and harmony as well as rhythm.
