The Sagrada Familia will once again resonate with music on June 10th, during a special mass commemorating the centenary of Antoni Gaudí's death. The event will feature 600 choristers, who will occupy the choir lofts specifically designed by the architect over a century ago.

This initiative aims to replicate the sonic impact experienced in 2010, during the temple's dedication ceremony attended by Pope Benedict XVI. At that time, the power of voices without amplification surprised attendees, showcasing Gaudí's acoustic vision.

The challenge of creating a suitable repertoire for the occasion has fallen to Juan de la Rubia, the basilica's titular organist, and Pere Lluís Biosca, the choir director. Choirs from across Catalonia will participate, including the Orfeó Català.

According to Esteve Camps, president of the Sagrada Familia Construction Board, Gaudí intended music to "elevate towards God" and designed specific spaces for different voice types: white voices above the altar, women's choir to the left, men's choir to the right, and the singing of blessings above the main entrance.

Galdric Santana, from the Gaudí Chair, explains that the architect conducted an empirical trial in 1921 to study the effect of large choral masses, seeking that "distant voices" sensation characteristic of romanticism.
