[Anguirel]

You'd expect Elrond, as Maglor's foster-son, to be a harper with a higher standard than most...I'd forgotten his harp. Well picked up.

We could even include, at a stretch, Gimli; his song of Durin was a kind of recording, I seem to remember he recovered the Book of Mazarbul, and he was as sundered from his folk at death as Dwarves can get...

But perhaps we should attempt to draw more conclusions from the solid examples we've got rather than contort other characters to fit the pattern. Though I do think Gimli just about makes it.

Another harper, Finrod Felagund, has a harp on his coat of arms and is renowned for his "song of staying" against Sauron, but...ouch...does not die apart from his people at all; quite the reverse. From this I deduce that he was more a doer of deeds in his art than a recorder of them...maybe...
