Hi, If this is the case, what is the deal with, say, cheap tubehorns composed of rubber hose or whatever. I'll admit to making a few of these in my day, and even to playing some copper tubes at hardware stores when I had my mouthpiece on me (college days). The one thing uniting all these beasts was that the harmonics were ridiculously skewed, beyond out of tune. It is also my understanding that one of the major challenges facing a horn maker is getting the harmonics - including the "standing wave" ones 1,2,4,8 etc in tune. How can we reconcile this "fact" with what you are saying, William (or any other physic gurus out there) Curiously yours, Marc _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
