The World Revolving

The World Revolving is originally in the key of C major. It is a battle theme from the video game Deltarune, composed by Toby Fox, the creator of both Deltarune and Undertale. The track plays during the boss fight against the character Jevil in Chapter 1 of the game. Toby Fox is also the performer and programmer of the music. A trivia fact is that Jevil's chaotic personality is reflected in the unpredictable rhythm and harmonic structure of the piece. The melody is fast-paced and dissonant, with irregular phrasing and use of chromaticism, contributing to the sense of instability and motion.
