The folk music of SCOTLAND is formed from a combination of Gaelic and Scots cultures.  Known in Scotland since at least the16th century, the Highland BAGPIPE is still in common use. It consists of a sheepskin bag in which are placed two tenor and one bass drone, a changer and a blow pipe.  The player fills the bag by breathing into the blow pipe, which then feeds a continuous stream of air to the reeds in the drone pipes and the nine hole changer on which melodies can be played.  The bagpipe is a versatile instrument used on ceremonial and military occasions for dances and for playing slow haunting laments.
