What is the title of the only musical episode of Buffy?

The only musical episode of Buffy the Vampire Slayer is “Once More, with Feeling.” It is the seventh episode of season 6, written and directed by series creator Joss Whedon, and originally aired on November 6, 2001.

The story begins when a demon named Sweet causes the people of Sunnydale to sing and dance their hidden feelings aloud. The supernatural format exposes secrets that the characters have been avoiding, including Buffy’s emotional distress, Willow’s manipulation of Tara, and the growing strain in several relationships.

The episode is unusual because the regular cast performed its own vocals, with some performers receiving less singing after expressing reservations. Its songs range from comic numbers to emotionally serious solos, making the musical structure part of the character drama rather than a simple parody. “Hush,” “The Body,” and “The Wish” are highly distinctive episodes, but none is a musical; they focus respectively on silence, grief, and an alternate reality.
