1585 – June 1640) was a German organist and composer, and member of the prominent musical Hasse family.
[citation needed] The first written record of Hasse dates from his appointment as organist at the Marienkirche in Lübeck, a post later held by Buxtehude.
Although virtually nothing is known of Hasse's early life, he is believed to have been a student of Sweelinck between 1606 and 1609.
Hasse remained in Lübeck until his death in 1640, and achieved considerable fame at the time as a teacher and performer.
After his death in 1640, Hasse's position as the main organist at the Marienkirche was taken by Franz Tunder.
