Reharmonization is the process of changing the chords of a song while keeping the melody the same. It's like giving an old song a fresh coat of paint by updating the harmonic structure. Think of it as remixing a song but focusing on the chords underneath the melody. The goal is to create a new and interesting harmonic context for the existing melody. This can result in a completely different feel and emotional impact for the song. Itβs a way to reinvent familiar tunes.
