French horn
A coiled brass instrument with a wide, mellow tone and a flared bell.
In Depth
The French horn, usually simply called the horn, consists of about 3.7 metres of coiled brass tubing ending in a large flared bell. The player's hand is placed inside the bell, which affects both pitch and tone color. The instrument is notoriously difficult to play due to its long, narrow tubing and close harmonic series.
The horn produces one of the warmest, most blending sounds in the orchestra and is equally at home with the brass, woodwind, and string sections. Its range spans over four octaves. Mozart, Beethoven, Strauss, and Brahms all wrote magnificent horn parts. The horn section in a full orchestra typically has four players, sometimes expanding to eight in large Romantic works.
The French horn is widely considered the most difficult orchestral instrument to play. Professional players miss notes more often than any other section — the instrument's physics make perfection nearly impossible.
