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.
