Daily Routines is a proven approach which has helped thousands of trumpet players grow in strength without having to resort to annoying high note methods. Daily Routines is NOT a high note method.

Range is a by-product of strength, and strength comes from very specific daily practice habits.

There is no need to stress over physical mechanics. The book is designed so that playing the exercises in the correct order automatically leads to proper physical technique.
