French composer and organist. Planson worked in Paris, and won motet and chanson prizes at the 1578 évreux composition contest; he may have met Dowland, who knew his work. He published two collections of chansons by himself and others, some in musique mesurée style, and others in which a treble melody is given a very simple chordal accompaniment, anticipating the air de cour. Along with other composers, including Lassus, he set some of the poet Pibrac's psalm translations.
