Today I found myself in the embarrassing situation of arriving at a rehearsal, contrabassoon in tow, without a single contrabassoon reed. Luckily the problem was easily solved—the reeds were literally just a few moments away, and I didn’t miss a note of rehearsal.
The problem, of course, is that the contra is a university-owned instrument, used by several student bassoonists, and so I don’t like to leave my reeds in the case. I just keep them in my bassoon case, with my bassoon reeds, and usually this works out fine since it’s rare that I go anywhere with the contra unless I have my bassoon along, too. But on the rare occasion that it happens, like today, I can easily forget to bring the reeds with me.
A number of years ago, when I started to get really serious about the doubling thing, I decided I needed a bag in which to keep my non-instrument-specific stuff. For example, in prior years as a dedicated alto saxophonist, I kept my accessories in my saxophone case: a metronome, a tube of cork grease, and so forth. When my instrument cases began to multiply, I found myself sometimes without an accessory that I needed. Buying more tubes of cork grease isn’t a big deal, but multiple metronomes can turn into real money for a college student. So I invested in a cheap messenger-type bag.
I only know of one etude book geared toward woodwind doublers, and it’s Chris Vadala’s Improve Your Doubling: Advanced Studies for Doublers (Dorn Publications, 1991).
