RE: [Hornlist] Intonation beats
Yes and no. Actually the rate of beating we might hear in an out-of-tune unison is equal precisely to the difference in frequencies. So, a 440hz + 442hz = beating rate of 2 hz. This beating is due to interference, and though we can't hear it as a 'tone' because it is too low a frequency, we still can call it a 'difference tone.' All tones whether in-tune or not will combine to create this kind of intereference. An in-tune perfect fifth creates a difference tone exactly equal to the fundamental of the overtone sequence in which they would form the second and third partials. The third and fourth partials, a perfect fourth creates the same difference frequency!. This phenomenon suggested the notion of 'intervallic roots.', incidentally, which might be a part of our hearing of tonal implications in some musical contexts, but I digress.. So, an in-tune perfect fifth is actually creating beats at a much higher rate than the out-of-tune unison. We won't hear beating of the sort we would hope for when tuning up when tuning up a perfect fifth, because the beating is so fast it generates difference tones in the audio range-- we hear them as new pitches rather than beating effects.

Re: [Hornlist] Intonation beats
Google "timo esser generator". Hit # 1 is a downloadable shareware tone
generator ("Test Tone Generator 4.0") that you can use to experiment with.
It can generate two tones simultaneously. You can change either tone by
note or by frequency. You can hear what happens when you change a 5th one
cycle per second (cent) at a time. Much educational fun.
You won't hear beats from an out-of-tune 5th because the difference in
frequency between the notes may be several hundred cps, depending on which
two notes you set. If you set the two frequencies only a few cps from
each other, you sure will. But, experience it for yourself.
For continuous tone production, check the Loop box on the top. OFF/ON are
on the bottom right. You get 30 days for free.

RE: [Hornlist] Intonation beats
Faster does not equal "more". You will almost always perceive the fundamental pitches as being most important, and therefore most noticeable if they're not in tune. An interesting explanation of temperament may be read here: http://www.kylegann.com/tuning.html and I'm sure there are others. -S- > -Original Message- > From: > [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] > du] On Behalf Of [EMAIL PROTECTED] > Sent: Sunday, October 23, 2005 9:09 PM > To: horn@music.memphis.edu > Subject: [Hornlist] Intonation beats > > Calling all intonation experts.When two horns playing a > perfect fifth are 5 cents off pure intonation aren't there > more intonation beats per second than > if they are off 5 cents playing a unison?
