Pipe Major Robert Brown

Pìobaireachd (often anglicized as pibroch; Gaelic for "pipe music") is the classical art music of the Great Highland bagpipe. It is characterized by a theme-and-variations form built on a ground (urlar) followed by increasingly elaborate variation cycles. The music is typically non-metric or flexibly pulsed, with expressive pacing, extensive ornamental movements (such as taorluath and crunluath), and a continuous drone from the bagpipe’s three drones. Tunes are often categorized as laments (cumha), salutes, gatherings, and battle pieces, reflecting ceremonial and commemorative functions within Highland culture. Pìobaireachd is traditionally transmitted both through staff notation and through canntaireachd, a mnemonic vocal system that encodes melody and ornamentation using syllables. The repertoire emphasizes modal melody (commonly mixolydian on the bagpipe’s A) and deep phrasing over harmonic progression.
