Ainulindalë, often referred to as the 'Music of the Ainur,' is a foundational myth in J.R.R. Tolkien's legendarium. It describes the creation of the world through a cosmic symphony performed by the Ainur, divine spirits created by Eru Ilúvatar, the supreme deity. Each Ainu contributes their unique theme, weaving together a grand narrative that shapes the universe. As the music unfolds, it gives rise to Arda, the world in which Tolkien's stories take place. The Ainulindalë illustrates themes of harmony, creativity, and the interplay between free will and destiny, setting the stage for the epic tales of The Silmarillion and beyond.
