In Europe, the
power grid configuration is so much better, the power
output is more consistant and the frequency drifts less.
Yeah, and each country uses its own type of plug, all mutually
incompatible. Sounds way more advanced. ;-)

Yeah, that's one thing that's always puzzled me. They've managed to
get their act together with a common currency. You'ld think something
like a common plug wouldn't be too much of a stretch.

Well, we've been through it all before and it would be much better to have a
standard. While we're at it, what's the chance of tuning mains hum up to an
actual concert 'A' or even down to a concert 'G' (about 46Hz by my
calculations). OK, I know what the realistic answer is, but how many times
have you wished that the mains hum was at least IN TUNE! :-)

Many a time here. Frankly, I even consider this discrepency a stress
contributor on the planet.
I wish we could get the U.S./Japan/etc to come down from 60 and Europe
to go up from 50 and split the difference at 55 Hz thus bringing the
planet back in tune.But then 440 isn't that solidly entrenched a
standard either.

You and I are of one mind on this subject!
No 440 isn't a solidly entrenched standard. If they tune to A446 or whatever,
that'll make Japanese mains hum about A#. I prefer the supposedly
'Pythagorean' tuning of A432, because the maths looks nice (I'm an artist not
a scientist :-). If a second is a natural division of time then it would be
generally more harmonious, surely? If the size of a second is arbitrary (I
don't know) then so is the entire argument. 55Hz would at least give a
'concert' A -3, which as a bassplayer would allow me to tune to my amp.
*laugh*
I would seriously like to see some proper research on the subject as I also
seriously think that the pitch of mains frequency does contribute to stress,
not just in musicians trying to tune their instruments. As such I would argue
for everyone pitching Down rather than Up. Just a thought.

The "size" (length, time) of a second is arbitrary..

Scientific pitch is based on a 1 second period: C = 1Hz.
(usually expressed as C = 256Hz but that's just a different octave)

Isn't it time we made sound systems that didn't generate power-frequency
hum in the first place? ;-)

Hmm, well that brought up some interesting pages when I Googled for it.
I'm interested in creating music based at this pitch for a variety of reasons
- one of my major motivations for wanting to use computers for music is to
explore the realms of intonation, pitch and temperament. I shall be compiling
scala over the holidays to that end. It's all relative I guess. ;-)
Thanks for that lead.

It was all the time 220V -+5%
Since every year it is more power required...
To get a lower load (Amperes) they have changed the AC to
1992 220V -5% +10%
1998 230V -5% +5%
2004 230V -5% +10%
and the in
2008 240V -4% +5%
Which mean, if I have a Computer which need 1000W prior to 1992 it had
4,54 Ampere.
And after 2008 it will be 4,17 Ampere.
