In Dulci Jubilo (Quasi Carillon)

Johan Beeftink (*1941) was teacher at the Groningen Conservatory for many years (but he'd just retired when I started studying), and he was one of the (assistent) organists at the Martinikerk.

This very fun to play piece consists of an ostinato in 5/8 against the chorale melody in normal 3/4 metre, which gives a nice polyrhythm.
