FIRST: Learn lip trills in the lower register and
learn to do them with lip, jaw, or tongue motion avoiding the use of changing
pressures as much as possible. Do not go to the extremes of fighting the
use of pressure as this could delay all progress; just concentrate on the
use of tongue, lip, and jaw.
SECOND: Learn to trill in all of the harmonic series
starting with F#, bottom space. Learn all seven positions starting with 1-2-3
and work upwards.
THIRD: Use the metronome! Start at a comfortable speed
and increase the speed on notch at a time to your limit. Do this on all
fingerings in all the series possible for you.
FOURTH: "Lip" as sharp as you can when practicing these
exercises, this is very important. These exercises should be worked up to
four notes per tick at 120. If you find that you are too tired to continue
above the staff, try starting on a higher harmonic, after you have gotten
to a fairly good speed on the lower notes. Quarter Note=80
FIFTH: When you can trill up to high C (from high Bb
to C) start a trill on the top line F# (1-2-3) lipping up and keeping your
lip in a fixed position. Push the trumpet toward your mouth and relax, push
and relax, go as fast as you can and as slow as you can. Try to have control
at all speeds.
