Thought I'd found a good page of info, here: http://stohrermusic.com/2011/11/how-to-choose-a-saxophone-mouthpiece/
3/4 of the way down, under "The tip opening" the author says: "The larger the tip opening, the more it favors the higher partials, thus the brighter the sound. A stiffer reed on a more close tip opening will give you a darker sound than a softer reed on a larger tip opening on the same model mouthpiece."
On another site, about halfway down, here: http://mouthpieceworks.com/Terms.html
"Tip Opening: The distance from the tip rail to the tip of the reed, usually measured in thousandths of an inch. Usually, players will use softer reeds on larger tip openings. Smaller tips get a more focused, compact sound while larger tips get a bigger, fuller sound. A larger tip takes more air and is less resistant."
So, the first guy is saying larger opening = brighter sound, smaller opening = darker sound.
The second guy is saying larger opening = fuller sound, smaller opening = focused sound.
I'm reading "fuller" as darker, and "focused" as brighter. In other words the two authors are exactly opposite in what they say!
Now confused, I thought the 2nd one was correct?
Anyone? Tom? Help!!
