A Diapason stop pitched an octave or two below unison pitch; i.e. 16' or 32'.

Major Bass is also a synonym for Contra Bourdon. Grand Principal is also a synonym for Grand Diapason. See also Sub Octave. Wedgwood alone considers Offenbass to be a synonym.

Three of these names are mentioned only by Wedgwood. Regarding Diaocton, he writes: �A 16 ft. pedal stop (Washington Temple, U.S.A.). = Major Bass.� Regarding Basso Profundo, he writes: �A deep-toned pedal stop equivalent to Major Bass. Milan Cathedral, 24 ft.� Regarding Pedal Pipes, he says only �see Major Bass.� No examples of these three names are known, other than those cited by Wedgwood. Wedgwood considered Major Bass to be a synonym for Contra Principal, but not Contra Bourdon.
