Can [magic mouth](https://www.dndbeyond.com/spells/magic-mouth) convey as a message a song (or at least something that resembles one)?

Its description states "...and **recites** the message in **your voice** and at the **same volume** you spoke".

A message that could be written as "nà, nananà, nà, nà, nà" could be "spoken" using appropriate volumes and tones for the individual words — that would be a melody. I mean, speech is a more complex thing than just "volume", since there is also the voice tone that varies frequencies.
