Clarke's first and second technical studies, played very softly, and for multiple repetitions....

Colin's *Lip Flexibilities*, volume 1, repeated with various fingerings, again played very softly....

Scales and arpeggios(major and minor) played one octave, slurred, then tongued, through the circle of fifths, all twelve keys(more than one octave if possible)....

Practice frequently, but for short periods of time(no more than 20 minutes per session, followed by at least 20 minutes of rest time), several times per day(up to six 20 minute sessions/2 hours of playing)...

Hope this helps...email me privately if you'd like more details....
