The Composition
Gregorio Allegri composed his Miserere mei, Deus during the 1630s (the precise date is uncertain, with estimates ranging from 1630 to 1638) for performance during the Tenebrae services of Holy Week in the Sistine Chapel. The work is scored for two choirs: a five-voice choir (SSATB) and a four-voice choir (SATB) that alternate verses of the psalm in a practice known as falsobordone (harmonized chanting). The famous soprano high C that has become the work's signature appears not in Allegri's original score but in the ornamental tradition added by the Sistine Chapel singers over the following century. A performance lasts approximately 12 to 15 minutes. The work was performed in near-darkness, with candles being extinguished one by one during the service, creating an atmosphere of increasing solemnity.
Biblical Text
The text is Psalm 51 (Psalm 50 in the Vulgate numbering) in its entirety, the great penitential psalm traditionally attributed to King David after the prophet Nathan confronted him about his adultery with Bathsheba and the murder of her husband Uriah (2 Samuel 11-12). The psalm's superscription reads: 'A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba.' Key verses include 'Miserere mei, Deus, secundum magnam misericordiam tuam' (Have mercy upon me, O God, according to thy lovingkindness, v. 1), 'Cor mundum crea in me, Deus' (Create in me a clean heart, O God, v. 10), and 'Sacrificium Deo spiritus contribulatus' (The sacrifices of God are a broken spirit, v. 17). The Latin text follows the Vulgate translation of Jerome. The psalm moves from confession of sin through petition for cleansing to a vision of restored worship - a theological arc that the musical setting mirrors with extraordinary sensitivity.
The Creator
Gregorio Allegri (1582-1652) was born in Rome and trained as a chorister at the church of San Luigi dei Francesi. He studied composition under Giovanni Maria Nanino, a pupil of Palestrina, placing him in direct lineage with the greatest tradition of Roman polyphony. Allegri was ordained a priest and joined the papal choir in 1629, where he served until his death. He was a devout churchman whose entire compositional output was sacred music. His other works include motets, masses, and concerti, but the Miserere overshadowed everything else in his output. He composed it as a functional liturgical piece for a specific ritual context - the Tenebrae of Holy Wednesday and Good Friday - not as a concert work.
Musical Analysis
Allegri's original setting alternates between the two choirs in a relatively simple falsobordone style: the four-voice choir chants its verses in block harmonies, while the five-voice choir responds with slightly more elaborate writing. The famous ornamentation - including the soprano's ascent to high C (C6) - was added by the Sistine Chapel singers as part of an improvised embellishment tradition called abbellimenti. The version commonly performed today is largely a reconstruction by the English musicologist Ivor Atkins (1901), based on accounts of the embellished tradition rather than on Allegri's manuscript. The harmonic language is modal, centered on the Dorian mode, with the simplicity of the underlying chords creating a canvas on which the soprano ornaments float with ethereal clarity. The alternation between the distant five-voice choir (traditionally placed in a gallery) and the closer four-voice choir creates a spatial effect of call and response that, in the Sistine Chapel's acoustics, produces an otherworldly resonance. The climactic high C, sustained pianissimo, represents the soul's cry of contrition reaching toward heaven.
Theological Content
Psalm 51 is the most important of the seven Penitential Psalms and holds a central place in Catholic, Orthodox, and Protestant theology of repentance. Its theology asserts that genuine contrition, not ritual sacrifice, is what God requires ('thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering. The sacrifices of God are a broken spirit,' vv. 16-17). The psalm's placement in the Tenebrae service - the progressive extinguishing of candles symbolizing the abandonment of Christ - connects David's personal sin and repentance with the cosmic drama of the Passion. The work's exclusive association with the Sistine Chapel invested it with an aura of papal authority and sacred mystery, reinforcing the Catholic theology of the church as mediator of divine grace.
Performance History
For over a century, the Miserere was performed exclusively in the Sistine Chapel during Holy Week, and the Vatican forbade its transcription under threat of excommunication. This prohibition was famously broken by the fourteen-year-old Wolfgang Amadeus Mozart, who heard the work on Wednesday, 11 April 1770, during his first Italian tour with his father Leopold, and wrote it out from memory afterward. (Leopold Mozart confirmed this in a letter dated 14 April 1770.) The English traveler Charles Burney published a version in 1771, and various transcriptions circulated thereafter. The work entered the general concert repertoire in the nineteenth century but was often performed in versions that bore little resemblance to Allegri's original. The modern performing tradition owes much to the 1963 recording by the Choir of King's College, Cambridge, under David Willcocks, which established the version most listeners know today.
Cultural Impact
The Miserere has become one of the most recognizable pieces of sacred music in the world, its soprano high C functioning as a cultural shorthand for transcendent beauty. The story of Mozart's transcription from memory has entered the mythology of musical genius. The work is regularly used in film and television to signify spiritual intensity: it features in The Passion of the Christ (2004), The West Wing, and numerous documentaries about the Vatican. The prohibition on its transcription - and the romantic story of its liberation - has made it a symbol of the tension between institutional control and artistic freedom.
Controversies
The primary scholarly controversy concerns the relationship between Allegri's original composition and the ornamented version commonly performed. The version with the famous high C is essentially a nineteenth-century reconstruction of an eighteenth-century performing tradition applied to a seventeenth-century composition. Purists argue that the 'authentic' Allegri is the simple falsobordone of the original manuscripts, while pragmatists note that the embellished tradition was already well established by Allegri's death. The Atkins edition (1901), which most performances follow, may not accurately represent the actual Sistine Chapel practice. The excommunication threat, while frequently cited, may be apocryphal or at least exaggerated; the prohibition was real, but its precise canonical status is uncertain.
Legacy
The Miserere established Psalm 51 as one of the most frequently set texts in Western music. Subsequent settings by composers including Josquin des Prez (earlier), Lotti, and Arvo Pärt all engage with the tradition Allegri's work represents. The piece remains a cornerstone of the Holy Week choral repertoire and is among the most requested works at choral evensong services in English cathedrals. Its cultural reach extends far beyond religious contexts: it is one of the most streamed pieces of Renaissance-era sacred music on digital platforms.
Recommended Recordings
1. The Tallis Scholars / Peter Phillips (Gimell, 1980) - a luminous, perfectly tuned performance that has become the modern reference recording, with the soprano Alison Stamp achieving a legendary high C. 2. Choir of King's College, Cambridge / David Willcocks (Decca, 1963) - the recording that brought the work to a wide audience, with the treble Roy Goodman (later a distinguished conductor) singing the famous top line. 3. The Sixteen / Harry Christophers (Coro, 2001) - a performance that balances historical awareness with emotional intensity, using a slightly different ornamented version.
