I never mastered circular breathing and being an engineer I figured I could design my way out of the problem. Unfortunately I used my artistic skills rather than my engineering skills and came up with this.
The clarinet pictured actually is (or was before manipulation) a Buffet C12. I am told (at Robert Gilbert’s where I bought it) that this model is built by an apprentice as the first run before they start building R13s. This makes it, technically, a masterpiece.
