On one day you are playing Brahms in an orchestra and the next you are playing Kenton in a club and the choice of sound is becoming a problem. One requires a soft and gentile timbre and the other a more edgy tone with an increased high range. One solution would be to change trumpets for each situation but at the cost of instruments today, who has that kind of cash. Another possibility would be to attempt to color your tone with your existing equipment but you will find this is only an act of desperation. This scenario was exactly what I was facing this past year. Performing classical music on the same mouthpiece I was performing our show in Branson was becoming a problem until I remembered my pair of Purviance mouthpieces resting securely in my endless collection of unused mouthpieces.
Switching mouthpieces for some people can be a problem because of the different size of the rim. The rim is the only section of a mouthpiece to contact the lip and because of this fact, changing rim dimensions, to some people is not possible with confidence. Because of this issue, the Purviance mouthpiece manufacturing company decided to offer two very fine mouthpieces with identical rim size and contours to their customers. And this was the beginning of the Purviance 4* and 5* mouthpieces. Each mouthpiece had the same size rims but the cup, shoulder, throat and backbore were different to accommodate two different playing situations; namely orchestral and commercial settings. The 5* produced a darker and more broad sound and the 4* just the opposite; a more edgy and focused tone. The more shallow cup and tighter throat and back bore on the 4* also helped to increase the players upper register required in a more commercial setting.
To some players, switching back and forth from a darker to a brighter mouthpiece may not be an issue, but for those forced to change tone in two different setting, the use of identical rims on two different mouthpieces may be worth looking into.
Shortly after the Purviance (two mouthpieces/ same rim size) offering came the removable rim. Removable rims meant that you could play on exactly the same rim and change the lower section to match the tone and range requirement. This was an even better solution for now you could keep your comfortable rim and change your tone as easily as changing your socks each day. Every mouthpiece manufacturer began offering removable rims in their catalogs and the trend took off like Maynard Ferguson playing “MacArthur Park”. Several of my fellow section players opted for this possibility and have stuck with it throughout their career.
One must face still two more decisions when performing on interchangeable rimed mouthpieces; whether you want your rim plated in silver or gold. This decision is something only the player can make for some players can tell the difference in feel and sound and to others, no difference is recognizable. To me, I can’t tell the difference and go with the silver every time. I will admit that a silver mouthpiece with a gold rim looks “way cool”. Also, people think you must know a lot to have something that different even though most people choose them because they look prettier. Another possibility of rim change would be more radical than just gold or silver. You may opt for a rim fabricated from something other than brass. Rims are offered in nylon, plastic and wood, just to mention a few. The thought of a nylon or plastic rim while performing with the Floyd Warren Orchestra at the Farm Progress Show in the middle of Winter in some unforgiving town in Iowa does sound more appealing to my now that I think back to that miserable job as the snow was blowing around us on a makeshift stage dressed in parkas with wind chill at 10 below zero!
I have reviewed the options of only the changing of rims but to add to the confusion, you also have the choice of changeable rims, cups, throats and backbores. If these weren’t enough choices, realize the possibilities if you wanted nylon rim, stainless cup, wood backbore in silver gold and polyurethane varnish!
No matter which option you decide, the possibility of “same rim/ different playing situation” may be in your future.
