What should two valves, one at the entrance to the added tube, the other at the exit from that tube improve ? When they first built the Viennese Valves, nobody had the idea to use the idea of the beer tap to construct a rotary valve, which does not rotate any way, but can be turned the one or the opposite way. Combining two of these rotors is a very delicate operation as it surely will make adjusting the valves double complicate. It also makes the horn ready for clumsy action by too many factors. I have not seen any such instrument, but I can imagine, that it was constructed to have both "half"-valves open "with the wind". But when closing the valve, the two halves will close "against the wind" anyway.
The reason to construct such, is the same always: to improve playing by modifying the hardware. If one has difficulties to slur from open note to a note not available as open note, they try to improve the valve action (opening). The invention of the valves was not very successful at the beginning & questioned by the composers, because the "software" (playing technique) could not be improved quickly enough. It was not the finger technique, it was the breath control needed for the "new" slurs. If this is not improved, -and many players are not able to control their breath enough to camouflage the defect of valve slurs- then no technical installation on the instrument would be able to help out. Just listen to some very few superb handhorn players, who treat their instrument in a way, one hardly can distinguish between open & "manipulated" notes. That´s it. ############################################################################################################################### Am 07.07.2010 um 06:02 schrieb [email protected]: > I tried to sketch out the idea (Vienna pumpen horns have 6 valves) > and I could see how it works, but if they're 8 rotor valves I'd > really like to see how they are arranged, if the concept really > works, and if it improves anything. > > I think the idea is to allow the air to go through all of the valves > regardless of what fingering you play so that valve combinations > don't 'feel' longer or different.
