[4][5][a] After this battle, Dagda discovered his harp hanging on a wall, in a feasting-house wherein Bres and his father Elathan were also.
The harp had two names, Daur Dá Bláo[b] ("Oak of Two Meadows"[8][10][c]) and Cóir Cetharchair ("Four-Angled Music"[11] or perhaps rather "Four-sided Rectitude"[12][13]).
[5][9] According to the Táin Bó Fraích [ga] ("The Cattle-Raid of Fraech"), Úaithne, the Dagda's harper, had three sons by the Bóand of the síthe, and the three sons became harpers themselves, each being named after Úaithne's musical strain, i.e., Goltraige ("weeping-strain"), Gentraige ("laughing-strain") and Súantraige ("sleeping-strain").
[19][21] The TBF narrative further explains: "The time the woman (Bóand) was at the bearing of children it had a cry of sorrow with the soreness of the pangs at first: it was smile and joy it played in the middle for the pleasure of bringing forth the two sons: it was a sleep of soothingness played the last son, on account of the heaviness of the birth, so that it is from him that the third of the music has been named".
Appears in the Symphogear anime series as a relic owned by Carol Malus Dienheim.
