Re: What\'s the difference/
Clila, do you believe you are hearing a consistent difference between organs in churches and those in concert halls? I have not heard many pipe organs live, as I've only been really interested in the last couple of years or so, but it would seem to me that perhaps churches generally have a more "live" acoustic profile than concert halls. Churches tend to have more hard, sonically reflective surfaces such as glass, stone, masonry, etc., while concert halls have carpeting, curtains, upholstered seats, and other such soft, sonically absorptive material. Of course the addition of many soft-bodied, coughing, wheezing, speaking-at-the-wrong-time
H. sapiens will decrease echo/reverberation in either venue, the church will still have a more "live" sound overall, even when full--or so I have noticed.
I was listening to my Karl Richter recording on the wonderful old organ in Victoria Hall (Geneve), before it burned down in 1983, and noticing that the amount of time needed for the sound to die away was very short compared to other recordings made in churches that I have been listening to recently. Of course microphone placement, organ construction, recording quality, etc. are all confounding factors, but I do think my assumptions / observations are generally correct.
Comments?
