Jacobus Vaet is yet another one of those renaissance composers whose early demise cut short a very promising career. He was probably born in 1529 either in Kortrijk or Harelbeke and was enrolled as a choirboy at Onze Lieve Vrouwekerk in Kortrijk aged thirteen. When his voice broke in 1546 the church gave him a scholarship to attend the University of Leuven which he entered in 1547. By 1550 he was serving the Emperor Charles V in 1550 as a tenor. He must have stood out because by January 1st 1554 he had become Kapellmeister to Archduke Maximilian of Austria – the future Emperor Maximilian II. He remained as Maximilian's Kapellmeister until his death aged 37 on Jan 8th 1567. Maximilian was generous to Vaet His death was mourned by Maximillian who wrote of it in his diary and by his fellow musicians many of whom composed elegies mourning his passing. His influence persisted after his death with many of his motets being used as the basis for Mass settings by a constellation of composers including his pupil Jacob Regnart, and such luminaries as Jacob Handl, Antonius Galli, and Johannes de Cleve. His Missa quodlibetica seems to have been the first of the genre and was used as a model by Regnart, Losio and Luython among others.
