Opus 56 was designed to be simple, yet elegant and flexible. It was the first Fisk organ in which a manual stop was made available in the Pedal by mechanical transmission, and the smallest to boast a full-compass 8′ Prestant.
The pipework is enclosed in a shallow mahogany case, which serves to focus the sound and to enhance the cohesiveness of its several voices. Hand-carved pipe shades ornament the graceful shape of the case, outlining the arrangement of the pipes on the windchest. The tonal design follows classic principles, giving the organ a rich, full organ sound on the one hand while allowing a diversity of timbres and tonal combinations on the other.
