Valveless scale exercise
So-called valveless scales can be found in several methode-books.
In "ASA-methode" by Rolf Quinque (Editions BIM, Suisse) he uses this
technique as preparatory exercises for high register training. A similar
study can be found in "The Art of Art Farmer", (Charles Colin, New York).
In these two books the exercises start on c2. For a beginner this can be too
high and strenous. By starting an octave lower, on c1, and developing that first,
it will be easier to finally play from c2.
(Note: This routine is based on a James Stamp exercise.)
Phase 1:
Play it legato and with normal fingering first. Then repeat several times with no valves.
Slowly at first.
Phase 2:
When the exercise (Phase 1) becomes easy to play, start the pattern from g1 (g1 - d2).
Phase 3:
When you can play Phase 2, finally start from c2 (c2 - g2).
This exercise can of course be played with the lips only and on the mouthpiece.
Note: Do not practise this too long. If you feel stiff, use some pedal-exercises
to relax the facial muscles. You could use an "opposite" pedal-exercise, where you
play a scale from low C down to pedal C "valvless" (only with open fingering),
or you could use this Warmdown excercise.
