Trumpet Lessons By Kurt Thompson
Frank Minear Trumpet

 

Frank Minear's Trumpet Method is a good practical approach with some good warm-up routines and daily routines. 

His main technique for building range is the 1 octave glissando. In my BRASS UPPER REGISTER PROGRAM, we use the 4 octave glissando which I believe to be more powerful in advancing high range and opening up the sound.
