French organist and composer of Flemish origin (1610-1684) who ran the court's religious music department with Pierre Robert until 1683. They were both promoted to the post of assistant music master at the Royal Chapel. From 1672-1673 Du Mont was the official Royal Chapel composer and was appointed master of the Queen's music. Apart from a few songs and pieces for harpsichord, organ and viola, he essentially wrote church music. He becme an accomplished composer, reflecting Renaissance polyphony and influence from the French air de cour and the Italian style, showing his familiarity with the music across Europe at the time. Although remembered particularly for his Masses, he showed perfect mastery of the art of counterpoint and successfully incorporated French and Italian styles. Du Mont's dialogue motets and grands motets are the summum of his skill.
