The harmonization of different musical styles created a unique sound.
Harmonization → It is formed from "harmonia" (from Greek ἁρμονία, meaning agreement or concord) and the suffix "-ization" (meaning the process of making or becoming). The word "harmonization" refers to the process of making things agree or work together in harmony.
Think of 'agreement' ('harmonia') and the process of making things work together ('-ization') — that's what harmonization means.
