Answer
Indonesian gamelan, with its intricate rhythms and shimmering timbres, profoundly influenced Messiaen's musical style. He incorporated gamelan-inspired patterns into his compositions, such as the "Mode de valeurs et d'intensités" in "Quartet for the End of Time," where each note has a specific duration and intensity. Gamelan's emphasis on layered textures and interlocking rhythms also resonated with Messiaen's interest in creating complex and immersive musical experiences.
