Jacob Obrecht (also Hobrecht; 1457/8 – late July 1505) was a Flemish composer of masses, motets and songs. He was the most famous composer of masses in Europe of the late 15th century and was only eclipsed after his death by Josquin des Prez.
What little is known of Obrecht's origins and early childhood comes mostly from his motet Mille quingentis. He was the only son of Ghent city trumpeter Willem Obrecht and Lijsbette Gheeraerts. His mother died in 1460 at the age of 20, and his father in 1488 in Ghent.
Details of his early education are sparse, but he probably learned to play the trumpet, like his father, and in so doing learned counterpoint and how to improvise over a cantus firmus. He is likely to have known Antoine Busnois at the Burgundian court, and certainly knew his music, since Obrecht's earliest mass shows close stylistic parallels with the elder composer.
