Rien Stein asks about glissando:

Rien: The basic trick in the gliss is to slide the keywork from closed to open
gradually (if going up in pitch) ever so smoothly shortening the air column to
raise pitch to the tone above it and so on, ever upward. It need not be done chromatically
to make the blend. Emboucher adjustment is coordinated with the gradual raising
of the keywork to affect a smooth "slide" without bumps or abrupt steps in pitch.
With just a bit of practice, emboucher and fingers will coordinate together nicely.
Going down in pitch is a bit harder. Wherever one finds a "bump" in his/her fin-
gering, the chromatic interval may have to be employed to smooth it out. If done
in a cadenza, a dramatic effect is to prolong the resolution to the top note, right
on pitch. I think it gives the listener the psychological reassurance that he/she
doesn't play that way all the time. Eddy Daniels does a "down" gliss so smoothly
that it gives the listener the eerie feeling he is passing through several octaves
of sound in reality, only one or less.
