Chorale in D flat major

Y'all are probably kind of tired of these by now, but last Friday in my history and literature of music class, my professor accidentally played the first two bars of a late Medieval motet by Dunstable (which I later found out to be his Quam Pulchra Es). I wrote this piece during the 50 minute lecture, and it turned out surprisingly well. I only had to make significant adjustments to measures 5 and 6 as I was assembling the audio file (these are almost certainly the most complicated in this piece). Anyway, in the style of late Medieval/early Renaissance music, I tried to use much less chromaticism (which turns out to be much easier to do in a major key).
