Interesting that you have posted this topic. Sorry for the delay! I hope that your student's surgery is going well.
I have been thinking about this recently in regards to a student leaving on a trip this summer. My hope is to put together some ideas in a more formal way, but here are some ideas:
I have written a few articles on practicing exercises with a bassoon reed and bocal and use of "drives." See:
"Using the Bassoon Bocal as a Diagnostic and Pedagogical Tool," Journal of the National Association of College Wind and Percussion Instructors 60/3 (Spring 1992): 4-7.
"A Bassoonist's Expansions upon Marcel Tabuteau's "Drive," The Journal of the International Double Reed Society 20 (July 1992): 27-30.
“Basic Bassoon Articulations,” The Instrumentalist 53/8 (March 1999): 28-32.
There are lots of exercises you can do with dynamics, articulation (great time to learn double tonguing!), and breathing. Speaking of breathing why not make this a time to master circular breathing.
Any how, if time allows I hope to put this quick notes together into an article. Let me know if you have any ideas as well. Terry
