Jehan Vaillant

Jehan Vaillant (; also spelled Johannes Vayllant) was a French composer and music theorist. He is named immediately after Guillaume de Machaut by the Règles de la seconde rhétorique, which describes him as a “master … who had a school of music in Paris”. Besides five (possibly six) pieces of music surviving to his name, he was also the author of a treatise on tuning. With Grimace and F. Andrieu and P. des Molins, Vaillant was part of the post-Machaut generation whose music shows few distinctly ars subtilior features, leading scholars to recognize Vaillant’s work as closer to the ars nova style of Machaut. Life and career Vaillant’s works are conserved in the Chantilly Manuscript, which is also the main source for the works of the Papal singers Matheus de Sancto Johanne, Johannes Symonis Hasprois and Johannes Haucourt. This connexion with the Papal group suggests to certain modern scholars that Vaillant may be the same person who entered the Papal chapel at Avignon as capellanus Johannes Valentis or Valhant on 26 November 1352, during the pontificate of Clement VI. This Vaillant died, still in Papal service, in 1361, probably of bubonic plague. The discovery by Israel Adler, the his
