"A brilliant design, accomplishes a great simplification for the left hand

-Chicago Symphony Orchestra Bassoon Section

The Weisberg System is a double octave key system that eliminates the need for "flicking" or "venting" while improving the pitch, tonal unevenness and preventing the cracking of the notes A2-D3 on the bassoon. It is currently in use in orchestras throughout the world and applauded by many of today's leading bassoonists.

Installation on most bassoons by appointment only. See our contact page.
