Derick Tormohlen i see that this is a pretty old comment...but if you still haven't found out to this day...it's composed by Ion Popescu Pasarea...Also...i don't want to say that i'm the best at singing but this wasn't a very good interpretation of it...There's a way better interpretation on youtube,which you can find in bogdanbdl 's video
This is a Orthodox chant, you can search on Google "Heruvic" is a Liturghy song, our Orthodox church doesen't allow Musical Instrument like Harp, piano, or guitar. At chant is a beautiful sound called "Ison" and you need to say "oo" in concordance with rythm of chant. If you want more Orthodox chant, I reccomand "Aparatoare Doamna"
