Mediaeval name, from »Bruden [Bruidhaen] da Derga«, mentioned in Flood's, »History«, chapter XXIII; In his »Story of the bagpipe« Flood states, however, that "in this old [i.e. 7th century] saga […] the band of pipers is designated cetharcoire, or the four-tuned" and that "Whitley Stokes is of opinion that cetharcoire has reference to the tuning of the chanter, the long drone, and the two reed-drones; but I [i.e. Flood] rather incline to the view that it means four pipes, inasmuch as the old Irish Piob mor [i.e. ➺ Pìob mór; ws] had only two drones".
