"Homeworld Waltz" is an instrumental song that plays in "Together Alone" during the ball that Steven, under the persona of Pink Diamond, held during his arrival on Homeworld in order to speak to White Diamond.
- Music: Aivi & Surasshu
- Surasshu provided the vocals for this piece, albeit heavily effected. He originally planned to use a Vocaloid-like Japanese vocal synth software, but felt that it didn't sound "hammy enough".
- This piece was inspired by "Draaiorgels" or self-playing/street organs.
- This is also demonstrated in the band that plays this piece during the ball.
- This piece has a combination of endless circle-of-fifth movement (which creates a shifting, dizzying effect) and extended resolutions (making it feel like it never ends/ends unpredictably) to create a bit stuffy but alien and weird music.
- This music was used at the end of promotional videos for the Diamond Days event.
