Little is known about Aagesen's early life but his musical mentor and spiritual adviser was Norwegian-born Jesuit Laurentius Nicolai with whom he studied music. Aagesen was appointed organist of Vor Frue Kirke in Copenhagen on 23 June 1593. He studied in Venice with Giovanni Gabrieli from 1599 to 1600.
