[Dixielandjazz] tubing

[Jim Kashishian]

Someone mentioned the length of tubing being used when one type or the other
type of fingering is used on the trumpet having an effect on the "color" of
a note.  You can really hear it on the trombone.  Try high Bb orC in first
position or in the alternate position of 3rd (3rd being about 6 inches out
on the slide).  Try Bb (top of staff) in 1st position compared to its
alternate position of 5th.  F in 1st vs F in 6th.
 
Tuning can be adjusted with the positioning of the slide, nevertheless, you
will hear a duller/darker sound in 3rd or 5th position.  Once again, though,
I don't know if the listener can hear that as easily as the horn honker can.
 
It's even logical:  there must be 15 inches of slide between 1st & 5th (no,
I haven't measure it, I'm just throwing my hand out there & looking at it!),
and that's down, and back = 30 inches.  Bound to have an effect on the sound
(timbre) of the note.
