Title: What is this tone hole alteration called?
Post by: DaveLeBlanc on November 07, 2019, 03:08:40 PM
This Charles Bay customized clarinet has this sort of tone hole modificationon many of the holes - what is the actual term used to describe it?

Hey Dave, it appears to be "chamfering" but I'm not 100% sure on that.

That sounds reasonable enough. I've never seen this before. it's kind of odd, and is seen on many of the tone holes here.

It DOES make a difference, however. I notice that the chalumeau notes are a bit more "open" and seem to project a bit more. Or maybe it's just a placebo effect

Some more research finds that this may potentially be considered "voiced" but I think that term is not specific enough.

Still, a "chamfered and voiced tone hole" sounds legit enough

Clark Fobes describes this for correcting a stuffy note in his article:
https://www.clarkwfobes.com/pages/tuning-and-voicing-the-clarinet
See "Example 7"
He calls it "cutting the wings" for lack of a better term.

I also found somewhere a reference to this method of improving a stuffy C#/G#. I've tried it with some success. But for many of the holes? It would probably correct for having lower than normal pad height, that's all I can think of.

The Fobes article, by the way, is practically a bible in itself. I was baffled by most of it a few years ago, but I go back to it occasionally to find that I am ready to digest more if it each time.

Thanks, Windy!

There are an extreme number of "cut wings" here -
F# pad
F# hole
C hole (just a bit)
Ab hole
F hole
F# hole
E hole

and "cut wings" on the crow's feet cutouts (I have NO IDEA WHY)

I suppose one has gotta respect Bay for being brave enough to do an irreversible treatment to like 7 of the tone holes.

How does it SOUND?

But ... But ... Beveling the crow's foot cutout ??? This is too much to ponder.

Just so I can stop pondering, I propose that he got a new reciprocating power-carving tool and was practicing with it. Did he do this on a GOOD instrument?

The host clarinet is a very nice 1975 Buffet R13. It sounds really nice, compared to a 1997 RC I think this one has more oomph on the lower end.
But maybe I’m just seeing things since the chamfered holes make a big visual impact and could be a placebo situation

As for the beveled crows feet - when have you EVER really needed extra space there???

I thought the "spread" on the lower RH pinky keys looks to have been widened a bit, maybe necessitating a bit of extra room there.  The newest Buffet Crampon I have is late 40s, but IIRC comparing it to others, that key cluster is a little tighter, so it makes sense that someone might spread them a bit.
