FRENCH HORN Horns are symbols of power and strength as were the horned beasts of elephants, bulls and boars - from which they were first made. The horn was originally used as a signaling instrument for hunting purpose. By the end of the 18th century, crooks were used to extend the compass of harmonics. The rotary_valve horn was invented in the early 19th century, and soon solved the problem of frequent changes of crooks in performance. The French horn is capable of a variety of tone colors that range from the warm & expressive to the rich & powerful.	Mouthpiece Tuning Slide Rotary Valve Bell
