The Original Patent of the Saxophone Mouthpiece
DESCRIPTION OF THE MOUTHPIECE
No. 9 (this number refers to the sketch of the mouthpiece on the patent letter.)
The mouthpiece of the bass saxophone. The other mouthpieces are then of the same proportions; one can of course make them a little smaller or a little bigger, if so one should wish.
