Re: Fobes CWF vs CF

The specifications of the two in terms of its facing length and opening are almost identical. The CF is listed as having a tip opening of .96mm (just a hair under 1mm) and a length of 17mm. The CWF has the same tip opening and a slightly longer lay of 17.5mm. If you were to use the same reed moving to the CWF the only difference would be that the reed would play slightly "lighter" in strength. Take a wooden ruler and hold it firmly against a desk with 9 inches hanging freely off the edge of the desk. Strum the ruler and quickly pull it in two inches. You'll HEAR the tone go up (it vibrates faster as the free length gets shorter.......same for reeds). Ideally you would ever so slightly want to take in a little (imperceptibly so) more mouthpiece with the CWF.

I was just discussing free blowing vs not free blowing with Brad Behn and I have come to the conclusion (for myself that is) that there really is no such thing. It really depends on HOW you play the mouthpiece (amount you take in and your embouchure "energy" vs the amount of air at any given moment) as well as the reed strength that determines how easy or difficult the process is. So I came to the conclusion that there is no such designation for mouthpieces in and of themselves.
