Hans -- You forgot fire! Without fire you cannot build a bell with a hammer. Returning to your earlier message, I'm inclined to agree that mechanical complexity has a cost. (The notion of adding valves to the horn was by itself something of a tradeoff!) But I can think of reasons why a builder might want to experiment with doubled valves. One possibility is that it would allow an air path without sharp turns. (But the typical Pumpenhorn does not exploit this possible advantage.) Hmmm. Consider the great step forward for the trombone when the Thayer valve was invented. (See http://en.wikipedia.org/wiki/Thayer_Valve) Has anyone ever experimented with these on a horn? It would seem mechanically unproblematic, except perhaps for devising adjustable valve slides. Such an instrument could respond more consistently with multiple valve fingeings. _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
