How do you go about choosing the right mouthpiece? More specifically, the right mouthpiece for you and the job you're doing. I've written a much more in depth article, which is on my website, about some of my thoughts isolating the components of a mouthpiece to hone in on what you need and want. Ultimately, the mp should help you get "your" sound out with the least amount of effort. Let's face it, most of us will end up sounding like we do on pretty much any mp. We've got a certain concept of how we want to sound so we can physically manipulate our tongue, oral cavity, lips, etc… to eventually get our sound regardless of the mp. I think the best mouthpiece choice for the job at hand is the one that helps you get that sound as easy as possible. If you've got a really screaming high and loud lead gig, chances are playing a 1C is going to be a lot of work for most people. Trying to playing a big symphony on a teeny lead mp is probably not going to be the right tool either. In my article I break down the components (rim, cup, throat, backbore) to try and concentrate on one thing at a time to see if that one component will work and you're on the right track, or if it's just not going to work. I think within the first few minutes a lot can be figured out whether the mp is going to be worth the effort to spend the time and learn the intricacies to play it, or it's just not going to work out. Then you need to ask yourself, what about that rim was working or wasn't, and why. Was it too sharp, to large a diameter and you felt like you were falling in too much, or was it way too narrow and cut off some lip vibration.
I'd love to hear comments, questions, anything on the subject, and encourage you if you're interested in reading the full article, to take a long. As well as rim choices, like I started talking about, I also address cup, throat, backbore, etc….
Happy mouthpiece hunting!!
