Composer whose name is probably an anagram of Trébol--a French composer who was in the service of Martin V of Aragon in 1409. His Hé tres doulz roussignolbelongs to the extremely popular genre of the bird imitation piece. Another unascribed version of the same piece (Ma tredol rosignol) seems somewhat contrasted in mood and style; the nightingale in the first, 4-part, piece is gentle and pensive while that in the second, in 3 parts, is gay and extrovert.
