The Mouthpiece
Please see the video below regarding the mouthpiece. This is the first screencast I’ve attempted, so I have many technical issues to work out, but hopefully you will find it useful.
A couple more resources you may want to take a look at:
A mouthpiece comparison chart from Schilke, and one including more manufacturers (you can click through the ten pages to get an idea of just how many sizes there are). These charts can be difficult to make sense of, but give you an idea of how complex mouthpiece sizing can be.
For most of us in this course, the mouthpiece that comes with our instrument will provide us all we need. As you progress you may want to experiment with some different models and see if it makes a difference on your playing.
A pdf of the powerpoint used in the video above is available for your reference.
