The Musical Spell is a spell cast upon Snow White's wish that made everyone in the Enchanted Forest (and Oz) briefly burst into song to express their emotions.
- Snow White
- David Nolan
- Regina Mills
- Magic Mirror
- Seven Dwarves
- Zelena Mills
- Emma Swan
- Killian Jones
- Everyone in the Enchanted Forest (except Rumplestiltskin)
- The spell ended when Regina stole everyone's singing voices, similarly to how Ursula's was.
- However, the spell remained in Emma's heart and was freed when she faced Fiona.
- It is unknown whether the spell reached every realm, as it surpassed the Enchanted Forest and hit Oz.
- Rumplestiltskin is immune to this spell, as "the Dark One doesn't sing".
- The spell created eight songs, sung by different people:
- Powerful Magic – sung by Snow White and David Nolan
- The Queen Sings – sung by Queen Regina Mills, as well as the Magic Mirror, Granny, Geppetto, the Dwarves, Snow and David
