Brandt, Vassily -- Orchestra Etudes and Last Etudes for Trumpet

This collection consists of two acclaimed series of study material for trumpet: Orchestra Etudes (which takes excerpts from the trumpet parts of well-known orchestral scores and develops them into study material), and Last Etudes (which consists largely of modulating scales). Both series are for the advanced student and offer invaluable material for the study of phrasing and for warm-up drills.
