"Pearl's Theme" is an instrumental song that first plays in "Gem Glow" when Pearl explains to Steven about mental relaxation, and activating his gemstone to summon his weapon. It also plays in the episodes "Together Breakfast" and "Secret Team".
"“Pearl's Theme” from “Gem Glow”, “Together Breakfast”, and “Secret Team”. We wrote this with little touches of impressionism and ragtime to fit her elegant but lively character. It starts off with a straight rhythm and falls into a jazzy swing!"
- According to a Reddit AMA with Aivi & Surasshu, one of this song's inspirations was Rachmaninoff's Prelude Op. 23 No. 5 in G minor. 
- A variant of this song plays during "Tiger Millionaire" when Steven is imitating Pearl, as well as in "Reformed" when Amethyst takes a "Pearl"-like form.
- This is the first song in the main series to not only directly reference Pearl, but a Crystal Gem as well.
- A variant of this song is played in "Historical Friction" when Jamie is portraying Pearl in his play.
- Aivi & Surasshu made a remix of the track that can be listened to here.
