At the heart of Inner_Spaces’ spring programming lies a sacred representation with the evocative title Miserere mei, Deus, taken from Psalm 50: a great and heartfelt prayer asking God for mercy, typical of the Lenten season, dominated by the themes of reconciliation and conversion. Many composers across different eras have left unforgettable pages setting the Miserere to music, including Gregorio Allegri, Jan Dismas Zelenka, Pergolesi, Arvo Pärt, and Michel Richard Delalande.

A sacred representation in two parts, each preceded by an introitus: Miserere and Stabat Mater. A musical journey that moves from the return to oneself—recognizing in God the liberating force from guilt—to the scene of Michelangelo’s Pietà, with the sorrowful Mother holding in her arms the body of the dead Christ taken down from the cross. A contemplative path, through musical language, entering into the supplication of the praying voice and the sorrowful weeping for the death of the Savior. A music that explores and penetrates the mystery of humanity and the mystery of God.

Psalm 50 is the prayer King David addresses to God to obtain forgiveness after the dramatic events that lead him to commit adultery with Bathsheba and to the killing of her husband, Uriah the Hittite, his loyal officer. David acknowledges his sin, which stands constantly before him, and enters into deep repentance, hoping for God’s forgiveness, fully aware that only God can wash him clean, purify him, and renew him.

Michel Richard Delalande’s Miserere mei, Deus is one of the pinnacles of Baroque sacred music: every word of Psalm 50 finds a musical counterpart carved with extraordinary dramatic force. The composer employs the refined and highly expressive vocality of his time. French vocal music under Louis XIV was born from a very precise idea: the voice must never lose contact with the word. Everything—tone production, phrasing, ornamentation—is designed to ensure that the text remains intelligible and that the melodic line never becomes autonomous, as happens in Italian singing. The timbre is straight, almost without vibrato, since continuous vibrato was considered a flaw, a sign of instability. The voice must be clear, bright, projected forward, with an emission that seeks not roundness but clarity. French prosody, with its final accent and closed vowels, imposes short, sculpted phrasing, closer to declamation than to lyrical singing. The melodic line never unfolds in large arches: it proceeds in small segments shaped by the text, with constant control of articulation. It is a vocality that rejects display, power, and virtuosity: everything is measure, control, elegance.

Another decisive element is the use of ornaments (agréments), which are not improvised but codified signs, an integral part of the writing. The tremblement, port de voix, pincé, tour de gosier do not serve to decorate but to give life to a line that would otherwise be too bare. They are brief, precise, obligatory in the points established by performance practice, and must be executed with a rapidity and clarity requiring a technique very different from the Italian one. It is a vocality that does not aim for pathos but for the nobility of gesture; not for power but for precision; not for melodic seduction but for the truth of the word.

Psalm 50 consists of twenty verses. In the succession of verses, Delalande alternates soloist and three‑voice choir in a highly contrasted manner. The soprano verses present a musical language in continuous evolution and inner movement, while the choral verses follow a homogeneous and static form built on an extremely stable harmonic progression revolving around the main degrees of harmony (tonic, dominant, return to tonic, move to the supertonic, dominant, tonic). The soprano soloist, accompanied by basso continuo, experiments in each new verse with a different musical mode, exploring new dramatic tensions through the expressive forms known at the time, with an adherence to the text that is difficult to match. In each verse, a surprising musical invention is renewed—always different and always perfectly calibrated to the meaning of the words.

At the center of the program, acting as a hinge and an opening toward other sonic dimensions, is the intervention of Sarah Davachi, a Canadian composer and performer among the most significant in today’s electroacoustic and instrumental scene. Davachi will present a performance titled Miserere Omnium, about 40 minutes long, on the Tamburini positive organ, enriched with electronic samples taken from a previous organ recording. Her work is distinguished by a contemplative approach to sound, based on slowness, micro‑variation, and timbral layering. In this context, the organ is not only a liturgical instrument but becomes a source of resonance, memory, and transformation.

Davachi’s performance unfolds as a sonic continuum in which frequencies expand and dissolve into the church space, dialoguing with its architecture and with the acoustic memory of the preceding pieces. The electronic samples, integrated with great discretion, do not interrupt the flow but amplify it, creating a kind of inner echo that evokes the spiritual dimension of the evening. Her intervention is not a parenthesis but a sonic meditation preparing the ground for the concluding work.

A second electronic piece by Ars Discantica, Introitus II, serves as a bridge to the final part of the sacred representation, which presents Giovanni Felice Sances’ Stabat Mater dolorosa for solo voice and basso continuo. The work belongs to the period in which Italian monody, emerging from the Monteverdian revolution, finds in the lament its most intense and recognizable form. Sances takes the medieval text of the Stabat Mater and places it within a highly concentrated expressive language: a sacred monologue built almost entirely over a descending chromatic ostinato bass—the classic lament tetrachord—which here is not a mere rhetorical device but the true architecture of the piece. The ostinato returns unchanged for almost the entire composition, creating a stable and inescapable harmonic space within which the voice moves with only apparent freedom.

Each vocal phrase is born from the tension between the melodic line and the inexorable descent of the bass: the voice continually attempts to rise, to open a glimmer of light, but is always drawn back downward, toward the gravity of sorrow. It is a structure that offers no escape, making the Stabat Mater a sacred lament in the deepest sense of the term.

The text, one of the peaks of medieval liturgical poetry, places the Mother of God before her crucified Son. Sances’ music seems to adhere to this Marian theology: the single voice becomes Mary’s voice, suspended between contemplation and anguish, while the ostinato bass is the weight of the Son’s death—immobile, inevitable, like a block of marble. The entire composition can be read as a sonic meditation on the Pietà: the mother supporting the body of her Son, an image that spans centuries of Christian art and finds in Michelangelo’s sculpture one of its highest expressions.

The vocal writing is that of Italian monody of the 1640s: a flexible declamation shaped by the word, alternating quasi‑spoken moments with brief cantabile openings. There is no virtuosity, no display: the ornaments follow Italian practice—improvised, brief, functional to the affect. The voice must maintain a warm, expressive line, with a natural but controlled vibrato, capable of exploiting the dissonances created by the chromatic bass to intensify the harshest words of the text.
