justinf Posted December 7, 2010 Share Posted December 7, 2010 Pierre posted a YouTube link featuring the Holtkamp organ at Christ Church Cathedral in Cincinnati a few days back. This instrument reminded me of the Holtkamp at my university, though ours was much smaller: Two manuals, exposed pipework, no enclosed divisions, setter board round the back. And yet, it was so thoughtfully voiced and blended so well that it could convincingly pull off much more music than its specification (which I can't find) would suggest. Listening to the Cincinnati organ, especially the Karg-Elert , I am impressed at how effective is the Pedal Cornet. Looking around online, I see Holtkamp installed a number of these Cornets, for example at St. Paul's Episcopal in Cleveland (at 16' and 32', in a Pedal division which also included a Compton Polyphone!), Houghton College, MIT's Kresge Auditorium, and elsewhere. Can anyone clue me in as to what makes a convincing Pedal Cornet, i.e. a resultant 32' and not the 4' or 2' reed? The organ at the church where I grew up had independent 10 2/3' and 6 2/5' ranks, plus a two rank Cornet at 5 1/3' and 3 1/5'; Added to the pedal flues these could add point and definition, a kind of exciting thrum which made me think of Cochereau's comment about the NDP mutations (especially the 4 4/7 Septième) sounding like a chorus of double basses. But in no way did our mutations give the impression of a low pedal reed. I imagine it must be necessary to add further harmonics to fool the ear effectively, probably at least to the septième, just as a manual Cornet demands a tierce. Would the Houghton College example at ten ranks extend this up to the quart, i.e. 16, 10 2/3, 8, 6 2/5, 5 1/3, 4 4/7, 4, 3 5/9, 3 1/5, 2 10/11? How far up the compass of the pedalboard are such Cornets effective, and what do builders do at the top end? It seems these Cornets, when done right, can add solemn grandeur by the bucketfull (as Stephen Bicknell wrote), so I'm surprised not to see more of them. Though I suppose David Briggs is working on it! Justin Link to comment Share on other sites More sharing options...
