Listening to François Couperin’s Leçons de ténèbres (1714) for the first time, I was struck by an uncanny familiarity. Amid the French Baroque vocal lines, the Hebrew alphabet appeared: Alef. Beth. Gimel. Etc. As a Hebrew speaker, hearing these letters in such an unexpected musical context felt both disorienting and deeply moving. How did they end up here?
The answer lies in translation. The Book of Lamentations, mourning the destruction of the Temple in Jerusalem, is structured as an acrostic, each verse beginning with a successive letter of the Hebrew alphabet. Since Greek and Latin translations could not preserve this pattern, translators added the names of the Hebrew letters at the beginning of each verse. Over time, this detail became integral to Catholic liturgy, with the letter names sung as part of the religious text.
Couperin’s Leçons, continues this tradition, setting the Lamentations to music for Holy Week’s Ténèbres service. I was intrigued by the presence of my own language in this distinctly French, Catholic world, especially as Couperin’s letter settings—set as long, meandering melismas—conveyed an expression that felt almost self-contained, as if communicating a message unto themselves. This connection made me wonder: beyond their structural role, could these letters hold deeper meaning?
As it happens, this exact question lies at the heart of Jewish mystical tradition. In Sefer Yetzirah, an enigmatic ancient Kabbalistic text, letters are not merely symbols or sounds; they are seen as the building blocks of the universe. The book is structured around the Hebrew alphabet and links it to the very fabric of existence, proposing that before the world was created, there were letters, and that the world is the result of the various combinations of these letters.
This idea became the foundation for Alphabet Cantata, a piece that reimagines Couperin’s Hebrew Alphabet setting while intertwining it with my musical reflections on the significance of letters, drawn from Sefer Yetzirah and its teachings. The piece opens by classifying the letters according to their relation to human anatomy, as heard in movements 2, 4, and 6. The focus then shifts to the combinatorial possibilities of the alphabet in various permutations—known as Gates—which generate mantra-like sequences of sound. Movements 8 and 10 introduce this concept, while movements 14 and 19 put it into practice, culminating in movement 23, in which the soprano enunciates the Tetragrammaton (the four-letter name of God) using all possible combinations of two vowel sounds. The only outlier is movement 12, based on a French quote from Jean-Jacques Rousseau’s Essay on the Origin of Languages, which contrasts the Kabbalistic approach with a sociological perspective on the origin of language.
