The International Horn Society recommended in 1971 that the instrument be recognized in English simply as "the horn". No other language includes a nationalistic reference for the name of the instrument. Here are a few examples of the name of the instrument in other languages:
- French: Cor d'harmonie
- Spanish, Italian: Trompa, Corno
- German: Horn
- Hebrew: Keren Yaar
- Mandarin: Yuan Hao
- Mouthpiece: A detachable piece of metal which comes in contact with the player's lips. A large number of different mouthpieces can be bought, each with a unique rim width, cup diameter, cup width and bore size. Mouthpieces can be made to be silver- or gold-plated. Typically, silver is for firm, dry contact and gold is for loose, wet contact.
- Lead-pipe: The pipe of which air enters from the mouthpiece and flows toward the main tuning slide.
- Valves: Keys which can be depressed to change the total length of the instrument.
- Pinky-ring: The curved piece of metal which the pinky-finger is placed in to help hold up the instrument. (Note: Some horn players have modified their horns and replaced the pinky-ring with another device that puts less stress on the pinky, allowing the rest of the hand to be more flexible)
- Bell: The large opening of which the right-hand is placed in and sound emerges from.
