This routine is the biggest key to my success.
It covers all of the fundamentals: high/low, loud/soft, slurred/articulated, flexibility, trills, multiple articulation, stopped horn, embouchure building.
I play this every day, and have for 28 years! The goal is long term growth, not perfection now. Do not practice a particular exercise until you feel it's great, play the whole routine and have it get better over 3 months, 6 months, 1 year, 5 years, etc.
I've added options for each exercise if you need some variety to the routine. If you do decide to change it up, for #1 - #4, if you choose the a option, then pick the a option for all of them so it keeps the symmetry of the dynamics/articulation in tact.
Ideally you want this to take you only about 25 - 30 minutes. In the beginning it might take you 45+. Just keep working on it to bring the overall timing down.
