While I was awake, again many angelic choirs were celebrating their Savior by their songs, and indeed, many at the same time, with a varying sound I did not understand, even though they were executing each and every note very clearly (for the more subtle or inward the subject, the better articulated it is). They were celebrating God the Messiah in different ways, and even though there were many praising at the same time, it was evident from the tonal modulations that there was wide variety among them. I learned what those varieties are in general, namely three: those who perform solely by visual portrayals; those who do so visually and at the same time vocally, which seemed to me to be very refined, sounding as if subtly winged [cf. 412] and as if they were the least of those who can be called lives; there are others who perform by voice only.
