Pìobaireachd

Pibroch, piobaireachd or ceòl mòr is an art music genre associated primarily with the Scottish Highlands that is characterised by extended compositions with a melodic theme and elaborate formal variations. Strictly meaning 'piping' in Scottish Gaelic, piobaireachd has for some four centuries been music of the great Highland bagpipe.

A more general term is Scottish Gaelic: ceòl mòr (in reformed spelling, or ceòl mór in old spelling), meaning the 'great music' (to distinguish this complex extended art-music from the more popular Scottish music such as dances, reels, marches, and strathspeys, which are called ceòl beag or 'little music'). This term encompasses music of a similar nature to pibroch, pre-dating the adoption of the Highland pipes, that has historically been played on the wire-strung Gaelic harp (clàrsach) and later on the Scottish fiddle, and this form is undergoing a revival.
