Celebrating the consecration of Florence Cathedral, Guillaume Dufay composed the motet Nuper Rosarum Flores in 1436. Drawing on spatial proportions derived from the dimensions of the Temple of Jerusalem as described in I Kings, every parameter of the work—pitch, duration, and form—was composed to instantiate an alternative spatial order: one present yet unseen. As Dufay’s composition resounded throughout the dome, the mystical space of the Biblical Temple was summoned within the strictly Euclidean space of the church through music.
Bellows is a concert-installation by Stefan Maier and Ragnhild May that seeks to instrumentalize a building—in this case, Église Saint-Eustache, a 16th-century church in the heart of Paris. Using a large spatialized loudspeaker array, feedback-based electronics, self-made instruments, a spatialized ensemble, and the grand Saint-Eustache organ—one of the largest instruments of its kind in France—Bellows explores the historical, mystical, and acoustic constitution of speculative space.
