Not that I got any sleep or anything (I exaggerate.) I'll be better soon. And right now I listen to a quartet by a favorite composer in a live broadcast, not something I get to hear so very often this piece except in recordings - I have one, which I heard back in college in its LP original and now have in its CD "remaster". Anyways.
Checked Mutopia. They do not have a Mozart work I've already begun - his "Hoffmeister" quartet - dedicated to, written for, a publisher friend of his, his string quartet in D major "Koechel number" 499 written in mid-1786. (Net connection decides to go down... whee... now it's back up.) I suppose since I've already begun that one, I'll just have to help them there...
(Lovely piece by the way. The article I began about it, changed and renamed since then though with the LilyPond file I added, is
here.
