What is "fraising." I saw the term in a description of some older Selmers. I think it has something to do with the tone holes.

Fraising is undercutting of the clarinet tone holes. This is done by hand with a tool which has a head shaped rather like a strawberry....the term fraising comes from a French word which mean strawberry. Undercutting gives flexibility to the sound and pitch, allowing the player to adjust his/her sound to others more easily.

Fraising and undercutting mean the same thing - a rounding or bevelling of the tone hole where it meets the bore. It reduces air turbulence at the corner and helps intonation. Slight changes of this area have drastic effects on intonation; in fact, undercutting tone holes on plastic instruments by someone who knows what they're doing can make those instruments sound (if not play) much better.
