The Church owns a Kawai R-0 grand piano, located inside the church, which is used on a regular basis for concert performances. Two other grand pianos, a Bechstein and an antique Steinway, are currently placed in other rooms on the premises – on the ground floor and the second floor respectively – and are used for rehearsals and small private musical events. There is also a vertical piano in the crypt, used by the JNRC for lessons and rehearsals.
