Gheyn, Matthias (1721-1785)
Matthias van den Gheyn (7 April 1721 – 22 June 1785) was a Fkemish composer from a family of famous bell-founders. Born in Tirlemont, Austrian Netherlands, he lived and worked in Leuven.
He is known first and foremost for his compositions for the carillon and the organ, though he wrote for the harpsichord as well. His eleven preludes (Preludio I-X and Preludio Coucou) are among the most frequently performed pieces on the carillon due to their musicality and technical virtuosity.
