Obrecht composed extremely quickly. He is supposed to have written one of his masses in one night. This was different to Josquin des Prez who spent a long time composing his pieces and making changes to them before he let anyone have copies. Obrecht was influenced by the music of Busnois and Ockeghem. Obrecht himself was a big influence on Josquin, even though Josquin was older than Obrecht.
