Allegri's Miserere is infused with a palpable sense of mysticism. And by mysticism I don't mean magic, or tarot cards or crystal prisms, or anything like that. I'm referring to the most traditional definition of the word itself: mystery of God. It brings your mind and your senses into a sacred space, and makes you aware that an infinite, boundless, and unfathomable Being exists.
There is a great deal about this piece that I am omitting from this posting, simply because it does have a lengthy and somewhat intricate history. This includes the contribution of another composer by the name of Tommaso Bai, and several different transcriptions that differ from the original version Allegri composed. That, however, takes nothing away from the beautiful resonance of this piece, or the accomplished creativity of its composer.
