What was it again? Concave, convex or the other way round? It doesn't matter since it just has to be round!
The internal hole of a clarinet is mostly cylindrical. On its upper and/or lower end, however, it is conically narrowing and/or conically opening.
To reproduce acoustic waves as naturally as possible, these areas will be drilled parabolically, i.e. with a slight radius, for all GEROLD CLARINETS from 2011 onwards.
For our professional model Amadeus de luxe, we even go a further step ahead; all sound holes are concavely undercut and/or open convexly towards the outside. Or is it the other way round? Well, that remains our business secret!
The only important and equally fascinating aspect is the fact that these tiny radii ensure a unique softness, smoothness as well as opulence and resonance of the sound.
Rony Moser, solo clarinet player at the Qatar Symphonic Orchestra, has called this unique sound a "creamy" sound... with this word, he got right to the heart of the concept!
