I believe it used to be long ago that blowing on pipe 1" in diameter and 12" long produced middle C. Presumably at an ideal of 256 cycles per second. While the metric system calculates volumes rather handily, I think the loss of the idea of a relationship between measurement units and vibration reduces it to the mundane.
I'm not quite sure what your last statement is in regards to
Hi David,
Very observant of you. I casually extrapolated the C4 label discussion to a greater dimensionality.
-- how would using C4 to indicate your described pipe create any more of a loss of relationship between measurement units and vibrations than calling that same thing c' does?
Neither nomenclature seems to me to describe your middle-C pipe very well.
Could be. The C4 notion is a flat declaration good for a few practical purposes. But say I describe a system which defines a system from the above and in the basic definition, octaves, like some organ pipes, go out in powers of 2. Then there is some superficial correspondence with C4 type of labeling possible. But if in the definition, the constant 2 is changed to be √2 or π, then we get into what I see as being rough territory for C4 because it doesn't have the notion of a pivot point and seems to me, can't entertain the notion of scalable octaves.
And now that I've caught up on the list mail, I think I have some empathy for Giovanni Andreani's remark about the Fixed Doh Napoleans.
