Tone hole Undercutting

Taken from THE CLARINET by Geoffrey Rendall

The holes of 18th-century clarinets, deceptively small to the eye, will
be found to be two or three times larger at the bottom than at the top.
This is a very ancient practice in wind instrument manufacture
It was found no doubt that. while a small hole was easier to cover,
conical ones have a better tone and more of it.
Further, when playing strongly, undercutting makes for easy blowing and
increased flexibility
The tone seems more directly under the fingers. It is, too, a valuable
means of sharpening a note without enlarging the hole at the surface
The practice is still commonly employed in making high-grade
instruments.
It is very necessary in an instrument with thick walls as a clarinet.
