French horn

Alto range brass instrument with a conical bore and keys to change the length of the tubing, and thus the tones available to the instrument, making it fully chromatic from the B below the bass clef to the F on the top line of the treble clef. This is a transposing instrument in F, so those sounded pitches would be written a fifth higher.See also horn.French Horna coiled brass instrument with valves, developed-particularly in France, hence the name-from the earlier hunting horn. often used in the orchestra, also in brass, military, and concert bands
