Organ installation and maintenance is not for the acrophobic. Here is the ladder leading to the entrance of the Swell division.

The Pedal division, played by the feet, contains the largest pipes of the organ (up to sixteen feet tall) producing the lowest pitches.

Wooden pipes up to sixteen feet in height produce a somewhat different sound than their metal counterparts. Here the Pedal Contrebasse 16' seen from below.

In April 2007 the tonal scheme of the organ as originally conceived by G.
Donald Harrison and the Aeolian-Skinner firm was completed with the addition of the Choir Unenclosed Trumpet, a gift in honor of Edith Ho's thirty-year tenure as Organist-Choirmaster by an anonymous donor. Organ curator Jonathan Ambrosino oversaw the replication of a Trumpet stop from a closely-related organ, A-S op. 943 of 1936 in the Wellesley College Chapel. The pipes were made by A.R. Schopp's Sons of Alliance, Ohio, and voiced by Christopher Broome of East Granby, Connecticut. Joseph Rotella of the Spencer Organ Co., Waltham, Massachusetts, designed, fabricated and installed the windchest. |

The horizontal Trompette en
Chamade, a gift in 1968 in memory of Ruth S. B. Dort, sits high above the west end of the nave. |
| In September 2006, new pipes were installed in the north gallery. The stop producing the lowest pitches on the organ, the Pedal Subbass 32', was left incomplete when the organ was built, stopping at low F. Through the generosity of an anonymous donor the lowest five pipes, down to low C, were added in 2006. Here they are in the process of being hoisted to their horizontal position in the north transept. |
