The Swell is the third manual up. Its pipes are enclosed in a box with shutters that can be opened and closed by means of a pedal, allowing the player to increase (‘swell’) or decrease their volume expressively.

Accordingly, it contains expressive stops for Romantic music: gentler accompanimental stops (nos. 33-6), characterful solo reed stops (46-7), and a thrilling reed chorus (44, 45, 48) that with the aid of the box can swell up and dominate the rest of the organ in spine-tingling fashion.
