A horn is a popular instrument in A Song of Ice and Fire for quick and easy communication.
A horn is often made from the horn of a horned animal, such as an aurochs or even a dragon.. Horns can come in various sizes. They can be banded with metals, such as bronze or gold. A dragon horn can have Valyrian glyphs written upon it. A warhorn's sound can be long and low and can carry far and wide.
Horns can be used to sound the alarum, to rouse camps, and to herald the coming of pit fighters. Sentries of the Night's Watch sound one blast when rangers return to the Wall, two blasts for wildlings, and three blasts for Others. p .

|“||Rory lifted his great horn to his lips and blew. AAAAhooooooooooooooooooooooooooooooooo.||”|
|“||A sentry's horn greeted them as they approached, sounding from on high like the cry of some, huge, deep-throated bird, a single long blast the meant rangers returning. ||”|
|“||AHooooooooooooooooooooooo, the warhorn cried, long and loaw, a sound to curdle blood. Asha began to hate the sound of horns. On Old Wyk her uncle’s hellhorn had blown a death knell for her dream, and now Hagen was sounding what might well be her last hour on earth.||”|
|“||The gate tuned out to be closed but not barred; it gave way at the second blow, and Ser Franklyn's men were halfway up the throat before a warhorn sounded the alarum from the castle proper.||”|
