The pipe organ in St. Catherine’s Church was designed and built by the Peragallo Organ Company of Paterson, New Jersey.

The 37-stop organ is played from a console of two manuals, each of 61 notes and a pedal-board of 32 notes.  The console is of French style, inspired by the Cavaille-Coll console at St.  Antoine des Quintz Vingts, Paris.  The draw knobs are positioned on terraces adjacent to the keyboards thus allowing the height of the console to be reduced.  The divisional draw knobs are of walnut with white engraving as are the coupler tablets above the swell manual.  The console is of oak.

The nearly 600 pipes, each made by skilled craftsman, are mostly made from a tin lead alloy, known in the trade as ‘spotted metal’.  The larger pipes are of annealed zinc.  Some of the pipes are of wood construction.  The pipes range in size from over 16’ in length to pipes the size of a pencil.  The pipes that are visible to the left of the altar are the pipes of the Great division.  Additional pipes, comprising the Swell division are located in a chamber directly behind the visible pipes.  The pipes of the Pedal division are divided between the Great and Swell divisions.  The dynamic level of the enclosed division is regulated by a series of louvers which open and close by use of a pedal on the organ console.

An additional feature of the pipe organ is the MIDI interface which brings the pipe organ into the 21st century.  The MIDI contains over 200 voices, 28 of which are available to the organist at any given time.  It is this addition to the organ that brings the authentic sounds of various orchestral instruments to the ensemble.

A Carillon was gifted to the church in 1999.  Built and installed by the Schulmerich Bell Co. of Sellersville, Pennsylvania, the Carillon brings the sound of true cast bells, as well as Flemish Bells, English Bells and Harp Bells, all of which may be played automatically, or by the organist from the console.  The Carillon rings the Angelus at noon each day, and rings again at 6 pm.  Weekend masses are announced by a peal.  The bells may be rung both inside and outside the church.
