Horn: Brief Description — Vienna Symphony Library
“The tubing of the Viennese horn is 55% conical and narrower than the most commonly used double horn in F/Bb. The so-called F crook is not a fixed part of the Viennese horn but is detachable. Other tunings are used especially for natural horn parts.“
Horn: Instrument Guide — Yamaha
“The horn is a brass instrument whose soft resonant timbre allows it to harmonize well with both brass and woodwind instruments. One of the unique aspects of this instrument is that the player keeps a hand in the bell while playing.”

“In the brass family, the French horn, or just horn for short, is easily identified thanks to its round body. It is constructed out of brass, a mix of copper and zinc, lending it its golden colour.”
