Diapason Phonon English?


A loud, large-scale Diapason, nearly always of 8' pitch, invented by Robert Hope-Jones. While Audsley claims that it is constructed in the same was as a normal Diapason, most other sources describe it as having leathered upper lips. Irwin describes the upper lip as having a roll of pipe metal, serving the same purpose as leathering, but being more durable. This treatment, according to Irwin, �gives it a pervasive, dull, round tone that is unfit for use as a base-tone for any type of Diapason Chorus.� He describes it as a solo voice, unfit for hymns or polyphonic music. Maclean describes its tone as �rich, full, and strongly foundational�, and says that it �blends well with other stops of similar pitch and character, but failed to combine effectively with upper octave and mutation ranks�.


Osiris contains ten examples, all at 8' pitch except for one at 16'.

Diapason Phonon 8', Swell; City Hall, Portland, Maine, USA; Austin 1912.
Diapason Phonon 8', Swell; First Church of Christ, Scientist, San Francisco, California, USA; Kimball 1924.
Diapason Phonon 16', 8', Great; Worcester Cathedral, Worcester, England; Hope-Jones 1896. Bonavia-Hunt considered this a particularly fine example.
