Re: Checking mpc table/curve accuracy

Does anyone have insight on what this actually means:

...from Foglietta
"The bore
of the M.(outhpiece) has to match the instrument. If it is too narrow as it often happens with cheap models, the whole intonation of the instrument becomes too high."

Does this suggest that the best intonation is achieved by matching the output bore (diameter) of the mouthpiece to the upper bore of the barrel? ...or matching to the main bore diameter of the clarinet (e.g. at the middle joint)? ...or the bottom of the barrel?...top of the upper joint?

Generally, all of these bores are different diameter on original designs. Most mouthpieces seem to have a taper (i.e. the diameter increases to the bottom). I have found that generally mouthpieces play flatter if they are larger bore, but there are exceptions. Some mouthpieces affect the width of the 12ths. Any 'words of wisdom' on this, or is my process of measuring and charting (with good tuner and warmed up instrument) the only real solution.

The same type of considerations go to choosing barrels, where information is also not available without purchasing and measuring...
