Cool Thumbs Up SmileyThis 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?

 

For people who don't know what a bow does - http://newt.phys.unsw.edu.au/j...../Bows.html

@ELCBK and others.  The main requirements of the frog are to keep the hair taught, retain the hair end, position the hair away from the bow shaft, counter balance the stick/hair, and as a reference point for finger position.  A secondary purpose is perhaps artistic expression. The most popular material is ebony, and I suppose plastic is a close second given the market share of the Glasser bow shaped object.
