(this page not available to non-members) ----oooo0000oooo----Did you know? - that while the Atlantic City Convention Hall organ, with its seven manuals and over 33000 pipes including ten 32 foot ranks and one 64 foot, is the biggest in the world, it is not the loudest. The Heldenorgel at Kufstein on the border of Austria, where the river Inn turns north into Germany, was built in 1931 by Oskar Walcker to commemorate German and Austrian troops who fell in the Great War. Enlarged in 1971 to four manuals, 46 stops and 4307 pipes, the Heroes Organ is now dedicated to the fallen of all races in all wars. It is situated under the roof of the Burgerturm on top of a bluff high above the town and the river, and 300 feet above the hut accommodating the console! Running at an extraordinary seventeen to eighteen inches w.g. (wind pressure, almost ten times the normal), it can be heard across the surrounding countryside and even on the peaks of the Kaisergebirge the other side of the river.

Peter Blackett writes:- "A few years ago ( before I joined eocs ) I saw on Tv an old film which was I think a Murder suspense type film. In the house there was a Pipe Organ and one person got murdered at the console. I think it could have been a 1930's or 40's film. I just wondered if anyone had any idea which film it might be?" Dave May wrote:- Can anyone please explain to me in simple language why a clarinet acts as a stopped (quarter-wave) resonator (overblowing the twelfth to obtain the upper register), while the other woodwind instruments overblow the octave, like an open pipe? Answers please to Dave May. Many thanks to Colin Pykett and Peter Blackett, who both answered my request. Colin said that (unlike the flute, which acts as an open pipe pipe half wave resonator and hence overlbows the octave) the reeded woodwind instruments act as closed quarter wave resonators. Thus the clarinet, with its straight bore overblows the twelfth, as one would expect. But because the oboe has a conical bore, it overblows the octave, despite being a closed resonator. Following up the link http://www.phys.unsw.edu.au/jw/clarinetacoustics.html which Peter gave me, from there I got to http://www.phys.unsw.edu.au/jw/woodwind.html#bores , which gives some usefully explantory pressure and displacement diagrams for open and closed resonators, cylindrical and conical. Colin says the maths behind the conical resonator is deep stuff, Bessel Functions and all that. ----oooo0000oooo---- Just a thought (from the EOM) - Middle age is when broadness of the mind and narrowness of the waist change places.
