We all believe in something, whether it's religious faith, trust in science, or simply belief in ourselves and the opportunities life offers. Rituals and traditions provide guidance in this journey – even for radical innovators like Messiaen and Stravinsky.

Messiaen found inspiration in ancient Greek poetry, Hindu rhythms, and birdsong, but also from peers like Debussy and Stravinsky. The constant: his unwavering, mystically oriented Catholic faith. From a modernist like Stravinsky, one might not expect a strong dedication to God, yet his Symphonie des Psaumes resonates almost like a musical icon.
