Very interesting and lovely dulcimer playing Daria! I'm not that familiar with these instruments but your style sounds a bit like listening to a cimbalom of Hungarian provenance to my ears... (very full and rich, thereby creating a wall of decay). Really like the sort of alienating effect on this kind of music... (or maybe I have it completely wrong, and this approach isn't uncommon at all?)!
Anyways, did I say that I like it a lot?

Being a Dulcimer player myself, I love that spelling mistake, when you describe the Dulcimer effect as ~ "creating a wall of decay"! ... or perhaps that's what you meant.
Anyway, it's especially amusing as it's not exactly the most popular instrument, when introduced to an Irish Session over here.
