This thread is SO COOL!  💖Love the carvings of the frog and scroll (ref to feeding the soul?).  The idea of a peep hole is just too much (ROFL) - like something I'd find hidden in my Grandmother's attic!

You've piqued my curiosity again, Irv - I was wondering if the ability to transfer or mute vibration was important when choosing a material for the frog?  

I found a nice scientific paper on the bow - great info, but it didn't really give me an answer.  Every inch of a bow seems to be made with the purpose of helping to produce sound, so I find it hard to believe that frog material is inconsequential - or maybe just the need for it (frog) to transfer vibration is?
