Season: 3
Hometown: Arlington, Texas
Members: 5
Result: Winners
Pentatonix is an internationally acclaimed a cappella group that won the third season of The Sing-Off.


Pentatonix has that special a cappella swag, something that most singing groups tend to lack. They can sing, dance, harmonize and put together a respectable arrangement in just minutes. The five-member group based in Los Angeles is very new, although some of the members were part of a trio that went to high school together in Arlington, Texas. The final two members were found on YouTube and through a mutual friend of theirs, just like that, Pentatonix was born. They have a modern style and draw influences from several underground electro genres, including dubstep and garage house. Pentatonix is hip and current, melding electronic music with pop hits and creating something that will make you want to dance and sing along at the same time.
