Well, it has been quite some time since my last mini exercise but here you go!
This exercise is a bit tricky to notate. The key thing is the concept behind the exercise. The act of moving the slide shouldn’t impact the way we blow. It is the *music* that should impact the way we blow. In the first two measures, move the slide quickly between 1st and 3rd position while blowing a steady stream of air. The quick slide movement shouldn’t impact the blowing action.
In measures 3-4, play a gliss with a steady sound. The slide should move quickly between positions but that steady air of the first two measures should result in a steady tone (no dip in volume as you change positions) throughout.
In the last two measures. Add the lightest touch of the tongue; just enough to conceal the quick gliss. Keep the air flowing throughout.
