Vocal Fusion is an attempt at meaningfully creating music together with AI. By using real time interaction and subdeviding vocal lines into melody and lyrics, humans and AI can create music together with shared agency. Vocal Fusion listenes to what chords or scales are played and adjusts the lyrics accordingly. For exmaple with a minor chord, the lyrics get more sad, and with major chords the lyrics get happier. Together melody and lyrics create one vocal line in real time, enabling real time music creation with human and machine.
