Galper's Vent and Register Key on Buffet R13 Bb Clarinet. Although I am not a dealer of this wonderful invention created by Avrahm Galper , I am so enamoured of the product that I have created this page to share more information about it based upon my personal experience. Increasing the length of the vent internally creates problems. Abe Galper has created a longer register vent by extending the vent outside of the body of the clarinet. This not only remedies the stuffy Bb problem but also makes the clarinet feel much more even-blowing in the upper register.
Uneven resistance is now a thing of the past.
In the months ahead, I plan to experiment to see if the vent and key can work with other Bb clarinets to enhance their responsiveness. I will post results, positive and negative, on this page. Since I am only one clarinetist and not a statistical sample, I will also post feedback, positive and negative, from other users about this product. Please send me your comments by email. Mr. Galper also served as principal clarinetist with the Palestine Opera Company, the Israel Philharmonic, the C.B.C. Symphony, the Toronto Philharmonic, and the Canadian Opera Company.
