Frank Zottola -- inventor & maker of mouthpieces for brass musical instruments
In 1952, while walking through a quiet New England woods he came upon a smoothly flowing stream. Subconsciously, his musician's ear noticed that it was producing a dark and diffused tonal quality. As he wandered along a little further where periodic rock obstructions on the stream's bed interrupted the water's flow creating turbulence, he became aware of the increase in brilliance and a compactness of sound. When the stream finally broke into a waterfall, crashing on the descending steps, the pitch, intensity and volume reached its maximum. At that moment, he had a realization that this natural phenomenon could be extended to a practical application in mouthpiece design. He postulated that a stepped back-bore design might very well be what contemporary brass players have been searching for to solve their problem of ever increasing range and endurance demands.
