Dumb question- what's the point of the soundhole rose?

Post by isleepinabed » Fri Jun 14, 2019 6:54 pm

I do apologize if this is just another dumb question but what's the point of the soundhole rose?

Just a visual embellishment and a demonstration of the builder's ability? I can't imagine it could improve sound (quite the other way around, surely)..

It dosn't effect the sound, and it's a traditional beauty feature.
A guitar without a rosette is like the the stem without a rose.

To be clear, I don't mean the rosette. I mean the "rose" that baroque and renaissance guitars seem to have. Usually a very intricate and thin wooden structure that obstructs the soundhole

Actually I learned a theory from Steve Ganz about the rosette worth sharing, if not the intent of your post. But maybe there is some similarity.

The rosette may serve to prevent cracks from propagating along the grain in the soundboard where exposed at the soundhole. Likewise, the wood strips (I forget the technical term) around the outside of the top and back can prevent the beginning of a crack in a vulnerable area.

And they are a beautiful fingerprint of the luthier.
All this time I thought I was making music; it was making me.

Bracing?
But the grain of braces and top is across so tends to split the top with humidity cycles?

Exactly. The soundhole rose is just a decoration, it has nothing to do with bracing, sound, etc. They were/are used also on lutes, ouds, and harpsichords.

To get back to roses rather than rosettes, I wonder if one practical purpose might have been to prevent the inconvenience of small critters trying to make a home in one's instrument, back in the days when they were far more commonplace in living and entertaining spaces.

This is as good of a guess as any.

Plus, they look pretty cool.

Hah.. that's certainly a new one... the impact of sanitation and public health on guitar design. Now there's a thesis waiting to be written...

To cut down on feedback. Medieval and Renaissance amplifiers and speakers were notorious for the problem, especially in the huge open spaces of their playing venues. :D

At its simplest a rosette is a ring of purfling. Virtually all spruce topped instruments are purfled at the edges - so it figures to protect the hole edge.. The intricate 'roses' and parchment 'wedding cakes' are bling - the flashier the rose - the better the price ?

The vermin screen make sence !
