LL> I've noticed that Dr. Dre tunes all of his with a at 453.5Hz, I've heard
LL> of people tuning down to a 432Hz but not up,Why does he do that?
LL> It has to do with ground hum at 60Hz in theU.S.A. Basically 60Hz
LL> is somewhere between Bb and B and by tuning up to 453.5Hz or so you've
LL> created something that will be in tune with the ground hum on speakers.
I finally got time to look up some of the information that I was waiting on
research time for, in order to study this a little better. I've been wondering
about it for awhile, for unrelated reasons... Crazy shit like current A
tuning allegedly being made uniform by Nazis looking to subvert organized
resistance amongst them through propagation via popular music, stuff like that.
:) I first found the discrepancies amongst tunings I think when I was looking
into some different diurnal beat stuff... Anyway, I thought it was kind of
interesting in a crazy way, but not too worthy of wasting my time with.
So when I saw you bring this here, and since I've been spending a little more
time with mathematical research lately, I thought I'd give it a peek. Bear
with me that this is strictly a mathematical opinion, as I still haven't been
working with music lately.
I'm making the assumption here that 'in tune with' is going to fall along the
the lines of beginning at an octave (that is a harmonic of) X60Hz, wherein 'X'
is an integer multiple, in order to remain along the harmonics of 60Hz. That
would place different semitones (ie your flat, note, and sharp thereof) along
the aforementioned octave at a ratio of 2^(1/12) frequency steps, to hit these
magic points.
So the question is whether or not 453.5Hz falls on one of those magic
increments. Unfortunately, I start work tomorrow, so I need to make sure that
I get some shit done here. ;) I'll try actually working the problem when I've
made some headway in increasing the efficiency of this place, and see whether
or not I can validate the claim that you brought up. :)
