Meloetta is a feminine humanoid musical bar-style streaks in its hair, quarter notes for its arms and hands and pupil-less eyes resembling whole notes (semibreves). It has a jewel on its forehead and a black headpiece that seems to be shaped like a treble clef which doubles as an attached microphone.
Meloetta is able to change forms when it uses the move Relic Song, which changes its form from Aria to Pirouette, or vice versa. In its Pirouette form, it is a dual-type Normal/Fighting-type Pokémon. In its Aria form, it has light blue eyes and flowing, green hair with light-blue ovals that resemble whole notes. In its Pirouette form, it has orange or red hair that seems to be stylized in a high bun and red eyes.
