Hi Jane,

Thats a great question although I’ve not seen any tests or evidence of the rosette contributing to the tonal signature, it certainly is possible. John Greven used to say anything south of the X intersection contributes to tone and anything north supports structure and prevents the top from folding itself into the sound hole.

I do believe the rosette helps to seal the open end grain around the soundhole edges. Quartersawn wood exchanges moisture with the atmosphere through its end grain. The top and back’s perimeter binding and the top’s rosette help to seal those end grain exposure surfaces.
