There are two kinds of binioù found in Brittany: the binioù kozh (kozh means "old" in Breton) and the binioù bras (bras means "big"), sometimes also called pib-veur.
The binioù bras is essentially the same as the Scottish great Highland bagpipe; sets are manufactured by Breton makers or imported from Scotland or elsewhere.
The binioù kozh has a one octave scale, and is very high-pitched; its lowest note is the same pitch as the highest on the great Highland bagpipe. It has a single drone two octaves below the tonic. In the old days the leather used for the bag was usually from a dog's skin, but this is nowadays replaced by other leathers which are easier to procure, like cow or sheep.
It is typically suggested by locals that the binioù originates originally from KernVeur (Cornwall in Breton). But as traditions in the country have died (as the mother tongue - Cornish), so it seems has the role of the Binioù.
