Great Irish warpipes

The Great Irish Warpipes are closely related to the Great Highland Bagpipe, with which they are now essentially synonymous. Historically the Irish Warpipes differed from the Great Highland Bagpipe by having only two drones, a tenor drone pitched one octave below the chanter, and a bass drone pitched two octaves below the chanter. Most players of Irish warpiper today play the three-drone pipes, the two-drone pipes having nearly died out.
