C Clarinet Extension

My extensions do not extend the range of the C clarinet. The extension fits between the bell and the end of the clarinet adding a properly sized and positioned tone hole to produce the E/B twelfth. Due to the much larger impedence of sound at the end of the clarinet the long B natural is often resistant and of a much different timbre than the throat tones. My extension greatly alleviates this problem - it also reduces the oversized twelfth interval. As a very happy coincidence the extension of the air column tends to even the timbre of both clarinets and produces a much more supple tone through all registers. C Extensions are available in blackwood for Buffet clarinets only.
