Abstract
A new right-hand, low register C-sharp key is provided for a saxophone, in addition to the conventional left-hand, low register C-sharp key. The saxophone may have the usual key shaft partially rotated by the conventional left-hand C-sharp key in order to open the low register C-sharp key on the saxophone. A new key is provided to be actuated by the little finger of the right-hand, which when actuated will open the same low register C-sharp valve, so that such valve may be actuated alternatively by either the right-hand or left-hand little finger. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
