The sopila is a wooden horn originating from Istria and some of the northern islands along the Adriatic Coast of Croatia. Like oboes, sopilas have double reeds, but are always played in pairs; one larger than the other. Both have six finger holes, being equally spaced on the smaller one, and set in groups of three on the larger one. Often used to accompany dancing, the voice of the sopila is that of the Istrian scale.
