'melodically' originates from the Greek word 'melōidía', where 'melos' meant 'song' and 'aeidein' meant 'to sing'.

'melōidía' transformed into the Latin word 'melodia', and eventually became the modern English word 'melody', from which 'melodically' is derived.

Initially, it meant 'a song or tune', but over time it evolved into its current meaning of 'in a tuneful manner'.
