The Kaval is an end-blown flute played across the Balkans and Turkey. It uses an embouchure similar to that of the Turkish or Arabic ney.
This is a very fine example, probably Bulgarian and made in what looks like plum wood with horn and plastic mounts. The lowermost horn mount has a couple of small chips in it, this is purely cosmetic.
It is playing exceptionally well with excellent intonation.The toneholes are ever so slightly scalloped, making it particularly comfortable to play.
