The House of Polyphony houses an ever growing collection of musical instruments to underpin its valorisation projects. The instruments are tuned and maintained by young professional musicians. Whenever it is deemed necessary, service by specialized restorers or instrument makers is called upon.
Currently the collection consists of
- Italian spinet, Jan Boon, Mechelen, 2001
- harpsichord Jan Boon, Mechelen, 2004, after Giuseppe Mondini ca.1700
- cabinet organ, Hans ter Hart junior, Amsterdam, ca.1840
- organ, Carlo Russo, Italië, 1713
- gothic organ, Walter Chinaglia, 2012, after a painting by Hugo Van der Goes, 1487
- harmonium, Christophe & Etienne, Parijs, s.d.
Besides these keyboard instruments, a series of instruments are kept on long-term loan: fiddle, hurdy-gurdy, dulcimer, renaissance percussion instruments, flutes and bagpipes.
