51B, day two

Today, I would like to present a basic description of the differences between the two mouthpieces -- the 4CL and the Schilke 51B -- so that perhaps some connection can be made between my playing differences and the actual physical equipment.

Mouthpiece	Rim Diameter	Cup Depth	Cup Shape	Rim	Throat	Backbore
Conn 4CL	26mm	Medium-Deep	V	Sharp	Medium	Large
Schilke 51B	25.63mm	Medium-Shallow	U	Soft	Small	Small

(Please note that I don't have exact specs for some of these things, and the "small" and "large" are comparisons to each other just from me looking at them. Someone really needs to make a large, complete mouthpiece chart with measurements! Links appreciated!)

With that out of the way, here are my notes for day two of my mouthpiece trial fun.

• I think I am really noticing the biggest difference in the rim style. It took me forever to get used to the sharp rim, and now going back is tough stuff. I think this is the source of my endurance issues. 
• Spent lots of time on long tones today. My chops feel like they're getting used to the size.
• Bb on the second line and down -- hard to get a good solid starting sound.
• Bb (tuning note) partial is sounding great. (My biggest complaint from my previous mouthpiece/playing.)
• It seems like it is easier to play louder, and takes less air in general. Bonus? Also, I think my mezzo-forte is generally louder on the 51B. Probably due to the smaller throat/backbore -- I am used to pushing a LOT of air with the 4CL. 
• My tone feels very bright. Jon once described my tone as having a bit of a "sizzle" to it -- I wonder if this is more like "dropping ice cubes into hot oil" tone.  

Overall, I like it. More chop time is definitely needed, but lots of things are just more comfortable. I don't feel like I have to work as hard at as many things. Isn't that what we all want, really?
