Miserere mei, Deus is a masterpiece by Italian composer Gregorio Allegri. The song was performed only in the Sistine Chapel in Rome, with the Papacy in Vatican keeping the score secret for more than a century. However, a 12-year old Mozart listened to the piece on a Wednesday and then transcribed it from memory, coming back on Friday to sort out minor errors – making him not only a genius but one of the first “pirates” in history, illegally copying music.
A Renaissance Masterpiece
Miserere (Miserere mei, Deus, Latin for “Have mercy on me, O God”) was composed sometime before 1638 for celebrations during the Holy Week (Easter). With soaring choirs and nine enchanting parts, it became an instant hit and it wasn’t long until Allegri’s Miserere was the only such work sung at these services.
Three authorized copies were distributed: to Leopold I (Holy Roman Emperor), the King of Portugal and Giovanni Battista (a leading composer of the time, for renditions). However, none of them managed to truly capture its beauty, because the secret of its relied on an elaborate performance technique, including improvised counterpoint – something which wasn’t transcribed on paper.
Basically, no one could ever play the song as it was intended except for the choir in Rome’s Sistine Chapel.
A Young Mozart Enters the Stage
Mozart’s father took the young prodigy on a 15-month tour of Italy to listen to some of the best musicians in the world and maybe study with Padre Martini in Bologna, who had also taught Johann Christian Bach – Johann Sebastian Bach’s son. But things got interesting way before the reached Bologna, as they arrived in Rome just in time for Easter.
As any respectable tourist, they visited the Sistine Chapel and happened to listen to the famous Miserere which was played there. After they got home that night, young Mozart quickly got to it and transcribed the entire piece – by memory. Three days later, he returned to listen to it again and make some minor corrections. His father was so excited that he sent his wife this letter:
“…You have often heard of the famous Miserere in Rome, which is so greatly prized that the performers are forbidden on pain of excommunication to take away a single part of it, copy it or to give it to anyone. But we have it already. Wolfgang has written it down and we would have sent it to Salzburg in this letter, if it were not necessary for us to be there to perform it. But the manner of performance contributes more to its effect than the composition itself. Moreover, as it is one of the secrets of Rome, we do not wish to let it fall into other hands….”
To make things even more interesting, Mozart transcribed it with the improvisation, making it more accurate than even the original transcription. After this point, details get a bit hazy.
It is historically mentioned that a few weeks after that, the boy met with the Pope and received a decoration, becoming a Knight of the Golden Spur. Some say it is exactly this transcription that earned him the distinction (instead of an excommunication). Others say he met with British historian Charles Burney, who obtained the piece from him and took it to London, where it was published in 1771. Either way, the ban was lifted after 1771 but only in 1840 was the complete ornamentation made public by the Vatican, many decades after a 12-year-old Mozart did it, alone, using only his brilliant mind.
To this day, Allegri’s Miserere is one of the most often recorded and played pieces of Renaissance music. In 2015 the Sistine Chapel choir released their first ever CD, including the 1661 Sistine codex version of the Miserere, recorded in the chapel itself, with the original acoustic. You can listen to an excerpt from it above, and hear a full version below, performed by the Tallis scholars. The full text, translated to English is at the end of the article.
Have mercy upon me, O God Have mercy upon me, O God, after Thy great goodness According to the multitude of Thy mercies do away mine offences. Wash me thoroughly from my wickedness: and cleanse me from my sin. For I acknowledge my faults: and my sin is ever before me. Against Thee only have I sinned, and done this evil in thy sight: that Thou mightest be justified in Thy saying, and clear when Thou art judged. Behold, I was shapen in wickedness: and in sin hath my mother conceived me. But lo, Thou requirest truth in the inward parts: and shalt make me to understand wisdom secretly. Thou shalt purge me with hyssop, and I shall be clean: Thou shalt wash me, and I shall be whiter than snow. Thou shalt make me hear of joy and gladness: that the bones which Thou hast broken may rejoice. Turn Thy face from my sins: and put out all my misdeeds. Make me a clean heart, O God: and renew a right spirit within me. Cast me not away from Thy presence: and take not Thy Holy Spirit from me. O give me the comfort of Thy help again: and stablish me with Thy free Spirit. Then shall I teach Thy ways unto the wicked: and sinners shall be converted unto Thee. Deliver me from blood-guiltiness, O God, Thou that art the God of my health: and my tongue shall sing of Thy righteousness. Thou shalt open my lips, O Lord: and my mouth shall shew (= show) Thy praise. For Thou desirest no sacrifice, else would I give it Thee: but Thou delightest not in burnt-offerings. The sacrifice of God is a troubled spirit: a broken and contrite heart, O God, shalt Thou not despise. O be favourable and gracious unto Sion: build Thou the walls of Jerusalem. Then shalt Thou be pleased with the sacrifice of righteousness, with the burnt-offerings and oblations: then shall they offer young bullocks upon Thine altar. Psalm 51Click here for reuse options!
