This is a good warm up because it forces your fingers to move.
This is a good lick to get your tongue working. If you are going to be playing a fast tune, you should definitely play this one.
In this Warm Up, Practice going from very quiet to very loud. For a harder challenge take it down an octave. Make sure the pitch stays the same. Don't go flat when you get softer.
This one relaxes your mouth. The more relaxed your mouth and body are, the faster you will be able to play.
When I attended a Master Class, James Galway gave me this one, it is a very interesting Warm Up.
Make up your own, A warm up lick should include tonguing, technique, and anything else that you will be playing.
