Temperaments...

All right.  I can see that the first-position notes would be related to one
another by the resonance of the instrument and would thus be in relative
just intervals (or very close).  But you have to begin somewhere, i.e. you
must tune your Bb to something.  And we indeed did tune our instruments
before every performance.

A-440 is the standard and for instruments that can play the A above middle-C
this is a no-brainer.  But for the trombone, playing A doesn't accomplish
much since you can position the slide wherever you want.  That's why it is
tuned in the first, closed position.  So that Bb is in tune with the other
instruments--and I mean in all keys--we always tuned to an ET Bb using a
meter.  Sometimes, in stage band play, we would tune to the piano for
convenience, but again this would have been in ET.  A-440 doesn't imply ET
in itself, but Bb-233.082 does.

I remember my grandfather tuned his saxophones, clarinet, violin and guitar
using a little tuning key.  It was a chrome-plated bar mounted to a base
much like a vibraphone with a single key.  It came with a little mallet and
was tuned to A-440.  We used to play with it as kids.  I often wonder what
ever happened to it.

B-flat is what it is, the F above that is a perfect 5th.  The D that comes
from the 5th harmonic is not an ET D, but rather a 5/4 ratio 3rd.  Of course
on the trombone you have the widest latitude for matching the correct pitch
of your ensemble, but the open (first position) notes are not tempered at
all.
