The upward gliss- It is appropriate that the upward
gliss should accompany or follow the "drop" or downward gliss because the
action of the lips and the use of the "half valve" (actually the valve is
generall pressed down only 1/3 of the way, but is widely called the "half
valve") is the same, although in reverse. This flissando is not used very
often in arrangements although there is some use of the "rip", an ornament
that is done upward through harmonic series hopefully landing on the "target
note". We will deal with the "rip" following the "upward glissando".
