In addition the organ has a full range of couplers, thumb and foot pistons and a detached console.

Each of the above names refers to one rank (set) of pipes with a particular sound eg flute. The length quoted, in feet, refers to the length of the pipe giving the lowest (deepest) note in that particular rank. The pitch of the notes produced by an 8ft rank of pipes is one octave above a 16ft rank, and one octave below a 4ft rank.

For comparison, the set of the notes produced by 8ft ranks of pipes is comparable in pitch to that of a piano. Apart from the length, which fixes the pitch, the tone is determined by the width, design and construction of the particular pipe.
