This assumes their memory can stretch back hundreds of years. I am in my late 40s and memories from my teens and 20s are still there, but they are fading. I don't remember names, specifics etc and I am certainly not "proficient" in things like hitting a baseball or diagram a sentence in English.
My guess is if I live another 940 years I will forget most of that completely ...... If I do live that long, I will come back on this board and post the results .... if I remember to.
Hmmm thats actually kinda cool - maybe Elfs memory is kind of a fuzzy indistinct ephemera and they create art and music as a means to soldify some of their faded memory into something that can prompt recollection.
Similarly maybe Dwarfs are drawn to stone because its a lot more sure than fleshy memory and when a Dwarf crafts a stone monument or a metal tool it gives them permanence in the world
