Thanks for all the great details and the link! I imagine tuning must be a bit nerve wracking and involve lots of constant testing, since carving the wood down is pretty irreversible.

Building your own musical instrument sounds like a daunting project at the beginning but one with very satisfying results. :)

Not knowing much about marimbas or woodworking, I’m super curious about the actual hand-tuning process! Is it carefully trimming the boards down? And how much do the tubes (?) at the bottom affect the tuning vs the wood pieces on top?
