IPA: /ˌmɒnəˈfɒnɪk/
KK: /mɒnəˈfɒnɪk/
Relating to sound that consists of a single melody without any harmony or accompaniment.
The song was performed in a monophonic style, featuring only one melodic line.
Monophonic → It is formed from "mono-" (from Greek "monos", meaning single or alone) and "phonic" (from Greek "phonē", meaning sound or voice). The word "monophonic" refers to a single sound or voice, typically in music where only one melody is present without harmony.
Think of 'mono-' meaning 'single' and 'phonic' relating to 'sound' — so monophonic means a single sound.
