Highland's organ, Casavant’s Opus 3771, consists of 44 ranks (2527 pipes) arranged in four divisions of three manual keyboards, and a pedal keyboard.

The pipes of the Grand (Great) Orgue are placed on the left and middle facade and are exposed. The pipes of the Pedal Division are exposed on the right facade with the largest pipes in the right corner area.

The colorful Recit (Swell) Division occupies the enclosed shutter section to the left behind the Great Orgue.

To Positif (Choir) Division is placed behind the grill in the upper right section behind the Pedal Division. Also housed in this section are the wooden pipes (Basson 16’) and the Subbass.

The organ was built to play the music of all the styles and periods. Its 34 stops are widely varied.

The four families of organ stops—principals, flutes, strings, and reeds—are well represented.

The distinct organ sound, which no other instrument can duplicate, is produced by the principals. This organ also includes Chimes, Harp, Celesta, and Clochettes (tinkling Bells). The old chimes are housed in our Bell Room.

The all-electric console, the bench, and pedalboard are made of maple. The interior of the console is oak. A blower with a 3 horse-power motor provides wind for the organ.

Scalings were done by Jean-Louis Coignet.

The organ was installed by Guy Leclerc and Marco LaFerrie.

Tonal finishing and tuning were carried out by Richard Marchand and Alain Gagnon.
