32ft on a manual

[David Drinkell]

I don't think there is.  I'm quite surprised that, among very large instruments, there aren't more manual 32' reeds compared to flues.  I should imagine that a manual 32' reed could be useful more often than a flue, even, for example, under a big principal chorus.

I should have thought that the opposite were true, David.

I found the short-compass 32ft. on the Primary G.O. at Norwich Cathedral quite useful, to underpin a sort-of grand Plein Jeu. However, a 32ft. reed, unless it was of very quiet fagotto tonality, would probably sound 'grunty' (it this is even a word). And, if it was that quiet, surely a well-voiced flue (such as a quiet mild string) would do the job equally well.

[David Drinkell]

A few things come to mind.  One is Bonavia Hunt's observation that a Father Willis-type Contra Hautboy would be an ideal 16' double for a medium-sized chorus (diapason too heavy, bourdon too thick, geigen too stringy, he said - I don't think quintatons came within his orbit).  I reckon that the same would apply to a 32' in a big chorus, adding gravity without too much thickness.  I've just looked it up, and I see that Donald Harrison had a 32' Contra Fagot on the Swell at Salt Lake City, which bears out what I am thinking - that a 32' reed would effectively broaden the effect of a large organ without thickening it too much.

One should not forget certain portions of the French repertoire, where both hands are high up on the keyboard and a substantial sub-unison is needed to keep the balance right.  Some large Cavaille-Coll organs have a sub coupler on the Great for this very purpose - I have one here and it comes in handy at the end of some French sorties, etc, even when the Double Open is already drawn.   Norman Cocker recommended a recipe for this sort of piece which involved drawing all the doubles and upperwork, but no unisons, together with any couplers that were available (which to him meant a full set on all manuals).

The 32' bourdon, which seems to be the most common manual 32', is essentially a thickener rather than an enrichener (?).  Peterborough Cathedral, before the last rebuild, could put out a prodigious unisonous mass of 32' bourdon, 16' diapason, flute and dulciana, 8' phonon, three diapasons a whole lot of other voices, etc.  It was very impressive in its way, although we might not do such things very often now.  In general, I find an open double more useful and less cloying.  I use the Great double open quite a lot - more often than the Swell Bourdon - and there is a nice little 16 Dulciana on the Choir which can add just the right amount of gravitas, even at 32' pitch when coupled.  Similarly, the open 32 at Liverpool is more useful than the bourdons elsewhere and I think an enclosed 32' reed might  be similarly handy.

There are one or two 2' manual reeds about (Leeds Town Hall - I can't think of any others, maybe they're even more rare than 32s), which expand the reed chorus upwards (I bet they're a pain to keep in tune, though).  I could see the point of a 32' swell reed to broaden the full swell downwards, both in its own right and to fully embrace a big Great when coupled.

Then there's the accompaniment aspect.  A 16' reed with the sub on can be handy in the psalms when there's a bit of smiting to be done or the weather is clouding over.  A quiet 32' reed would be fun, especially with the right assortment above it (every organ should have a Vox!).

Finally, if there's a soft 32' reed on the manuals, it's going to be useful on the Pedal.  The enclosed Contra Trombone at Redcliffe can come in very useful.

I think one or two American megatheria have 32' gambas on the Swell.

Perhaps someone more expert than I might clarify but apparently Dom Bedos recommended 32ft on manuals and there is one built into the modern instrument at Rieti. . . .

The Dunedin Town Hall organ in New Zealand has a 32' reed (TC) on the Swell. The rank is a 16/8/4 unit reed. That organ has 3x 16' reeds, no actual 32' reeds.

Jean Guillou's organ in St Eustache has a 32' Contrebasson in the Récit.

Indeed.

I have played this instrument once (with Guillou registering for me), although I cannot particularly recall the effect of the 32ft. reed on the Récit. (Or even if I actually used it.)

With regard to 2ft. clavier reeds - I can only think of one example; the Clairon Doublette on the G.O. of the Cavaillé-Coll instrument in S. Sernin, Toulouse.

Surely in order for this to be effective, the reed in question would need to be of slender scale and with the minimum of tonal 'body' (which would, arguably, make it rather less suitable at its own pitch) - otherwise the sound would be muddy and heavy. I have to avoid this type of registration on my own church instrument for this very reason. The Swell Double Trumpet is not small in scale and, if I were to use it with the Sub Octave coupler, the result would be thick, gritty and unpleasant.

[David Drinkell]

Small-scale and fairly free, I think.  After all, an organ which ran to such a stop would have something else for the big 32' pedal reed effect.  I'm thinking more growl than mere flatulence....

It would certainly have to be a fairly large instrument; even with a half-length bass octave, the expression box would need to be quite large.
