The Pony Tones

The Ponytones (or Pony Tones) are a vocal quintet who appear in Filli Vanilli. The group is initially a quartet consisting of Rarity (soprano), Big McIntosh (bass), Toe-Tapper (tenor), and Torch Song (mezzo-soprano or alto); Fluttershy later joins the group as a part-time fifth member.

Depiction in the series
The Ponytones are a singing ensemble of ponies who perform for various social events and charities in Ponyville. When first introduced, they are to perform for a fundraiser that Fluttershy organizes for the Ponyville Pet Center. However, prior to the fundraiser's scheduled time, Big McIntosh loses his voice during a turkey call competition. Using a potion that Zecora brews from poison joke leaves to deepen her voice, Fluttershy sings for Big Mac behind a curtain (suffering from stage fright) while Big Mac lip-syncs.

As a result of their performance at the fundraiser, the Ponytones are approached to give additional performances at a little filly's cute-ceañera, a ribbon-cutting ceremony hosted by Mayor Mare, and Cheerilee's class of school foals in the Ponyville Schoolhouse. With each performance given, Fluttershy's confidence in herself rises, but she also starts improvising her part, making it difficult for Big Mac to keep up with her. For their next performance at Sugarcube Corner, Big Mac recovers his voice, but agrees to let Fluttershy sing for him one last time. However, Fluttershy gets carried away and exposes herself; despite her embarrassment, her performance is praised.

Toward the end of the episode, Fluttershy joins the Ponytones as a fifth member, privately performing at her cottage for her pony and critter friends. However, she declines making public appearances with the band, citing the "baby steps" she is taking to overcome her stage fright.

The Ponytones' most notable song performed is Find the Music in You. They later reprise the song with lyrics from Fluttershy's Music in the Treetops.

Storybooks
In Rarity and the Curious Case of Charity chapter 1 "A Pony of Prominence", the story's narration mentions the Pony Tones as having only four members.

Fluttershy's Big Show is to involve the Pony Tones Quartet as in Filli Vanilli.
