[Hornlist] Re: slow air
Steve Mumford: Don't forget, we put air into the horn at what? maybe 30 miles an hour let's say, but the sound goes through the horn at something like 700 miles an hour. It's not the air that's making the sound. With a little practice, you can play by sucking in instead of blowing out (who needs circular breathing!) I do not agree, as this post seems to show a confusion between different things. For a string player, doesn't the speed of the bow matter? But that, too, is much slower than the speed of sound. The means for the production of sound is one issue, sound propagation is a different one. -- Daniel Canarutto mathematical physicist dedicated amateur hornist ___ post: horn@music.memphis.edu unsubscribe or set options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
Re: [Hornlist] Re: slow air
It's not just the speed of the bow but how lightly or heavily the bow presses against the string as the horsehair rubs the catgut. As my old horn teacher used to say, The motion of the air into the horn is like the movement of the violinist's bow across the strings. More air! His short version of that was, More air -- always, More air! (Not necessarily faster air, not necessarily higher air pressure, but larger volume of air -- i.e., more air.) Regardless of whether there is any accuracy, in physics or acoustics, to the analogy of air bow, the idea is helpful in performance nevertheless.

RE: [Hornlist] Re: slow air
It might be instructive to hear from those who understand the science of music and the horn to explain the difference between the volume of air moved through the horn and the velocity, how they are related and what each contributes to the music a horn produces. ___ post: horn@music.memphis.edu unsubscribe or set options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
RE: [Hornlist] Re: slow air
But not blowing more air through the horn !!! Just releasing more air or less air. If forte is requested, get the air a bit precompressed inside the body, so it escapes with more tension speed. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alan Cole Sent: Friday, April 29, 2005 2:01 PM To: The Horn List Subject: Re: [Hornlist] Re: slow air It's not just the speed of the bow but how lightly or heavily the bow presses against the string as the horsehair rubs the catgut.

[Hornlist] Re: slow air
My point was, that it's not the air traveling through the horn that makes the sound, rather setting up a resonance of the air column within the horn. Excessive air speed can actually interfere with that resonance, the sound wave has to travel forth AND back. It is actually possible to play the horn without passing any air through it at all. It's been done with a mouthpiece that has a membrane blocking access to the horn and a hole in the side to let the air escape. Sounds fine! As a practical effect, once I stopped trying to play so damn loud (everybody had to play LOUD in the 70s), I was able to play much louder but not quite so ugly. - Steve Mumford ___ post: horn@music.memphis.edu unsubscribe or set options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
