As I understand it in most of the world the instrument is simply called 'horn' and only Americans call it french. When I studied music in college I mostly heard the instrument refered to as 'horn' and only was called 'french' when necessary to distintuish it from horn as a general term for any brass instrument.

The hunting horns used in France are a predecessor of the modern horn; perhaps that is where the national designation came.

Early horns were 'natural' horns that could only play notes in the overtone series (similar to the way a valveless bugle is played). In order to play in different keys horn players inserted crooks. The first valved horns were used so musicians wouldn't have to deal with multiple crooks. The French version of the valved horn was a small horn with piston valves; the German version was a larger horn with rotary valves. The large rotary valved German horn is what we think of as a modern horn so it would probably be more accurate to call it German than French.

yh but im english and live in england and my music teacher is english so why wud he call it the french horn if only americans call it that?
