F/Bb Double Horn · Model 203ST
The double horn has established itself as the orchestral instrument of choice. The combination of full Bb and F horns offers the musician great flexibility in intonation and tone. There is also a definite correlation between mass and tonal projection. With full double horns the thumb valve serves to change to either the shorter Bb horn or longer F horn.
Some double horns are built according to the French “ascending” system, in which the third valve raises the pitch (in F as well as Bb) by a whole tone.
