While I certainly appreciate the length of the explanation of various woods, I d respectfully like to disagree strongly on the underlying premise - that density of the wood is what’s important for the sound. In fact the better sounding woods such as Mpingo wood, maple and spruce, to name a few, are not particularly dense. I could post the table of wood densities but I’ll leave that for the student. It might have been I who mentioned ironwood as I often use that wood as an example of a very dense wood that doesn't do much for the sound, as a form of irony. Get it? Of course ebony has a wide usage in musical instruments as well as Mpingo discs and other audiophile products. I used to have an ebony turntable clamp product myself way back when.
