RE: A = 440 Hz OR 432 Hz?

Hello Per e.a.l (Et Allied Loopers),

Interesting discussion!
I can be wrong, but my first impression is that if you transpose every 
string by the same amount, the microtuning (meaning intervals) does not 
change.
When you tune in DADGAD (Led Zeppelin) or other open tunings, the 
intervals across strings change.

Putting it that way is based on the assumption that certain frets on
the guitar equals certain notes. I'm not sure I agree with that
concept. I think that if you tune down a guitar one half-step you are
not changing the note A but rather moving every note of the fretboard
one fret closer to the bridge. The fret "formerly known as A" would
then play the note G#.

Some guitar players and wind instrument players prefer to name notes
from the fingering on the instrument rather than from the resulting
vibration in sound. I guess the name "Eb tuning" draws on that
perspective. But an interesting aspect of changing the strings pitch
on a guitar is that only the sounding notes are transposed but not the
full tempered-tuning-shebang system. So the result will be a different
micro tuning of the guitar.
