The trembita (from the old Germanic trumba, "to trumpet", in Ukrainian трембíта) is a type of an alpine horn made of wood.

It is common among Ukrainian highlanders Hutsuls who live in western Ukraine, eastern Poland, Slovakia, and northern Romania.

A trembita was used primarily by mountain dwellers known as Hutsuls and Gorals in the Carpathians, it was used as a signaling device to announce deaths, funerals, weddings.

The tube is made from a long straight piece of pine or spruce (preferably one that has been struck by lightning) which is split in two in order to carve out the core.

In the hands of a skilled composer or arranger, the natural harmonics can be used to haunting melancholy effect or, by contrast, to create a charming pastoral flavor.
