Ditch constant loops, match music to motion

Music should complement and enhance animations. Because animations have varying pacing and emotional shifts, a constant loop will fail to adapt to these changes, limiting the ability to create emotional depth and nuance, and resulting in a disconnect between the visuals and audio. Furthermore, a constant loop, even if initially pleasant, can quickly become grating and irritating.
Instead of repetitive loops, use variations in melody, harmony, and instrumentation to create a dynamic and engaging soundtrack. Incorporate transitions that match the pacing and emotional shifts in the visuals.
