Maistre Jhan (also Jehan, Jan, Ihan) (c. 1485 – October 1538) was a French composer of the Renaissance, active for most of his career in Ferrara, Italy.
An enigmatic figure, of whom little biographical information has yet emerged, he was one of the earliest composers of madrigals as well as a prominent musician at the Este court in the early 16th century.
He wrote in most of the genres current in the early 16th century, including, in sacred vocal music, masses (all but one of which are lost), motets, and lamentations.
In style the sacred music is similar to the work of Josquin des Prez (died 1521), using imitative passages alternating with homophony.
In 1542 three of his madrigals appear alongside composers such as Costanzo Festa, Francesco Corteccia, and Hubert Naich; the style of his works is similar to that of Verdelot, and represents the earliest stage of the genre, before it developed its peculiar individuality.
