Bom karnai, low trumpet.
The karna originated in Persia and its use spread across Central and Southern Asia. It survived as a military instrument in Persia until the early 20th century, but is now only found in Tajik and Uzbek cultures in Central Asia. Examples such as this one, made in the Fergana valley in Uzbekistan, are known as karnai, and publicly herald a number of celebrations such as weddings.
