Who Were the Original Members of Pentatonix

Who Made Up the First Pentatonix Lineup

The original members of Pentatonix are Scott Hoying, Kirstin Maldonado, Mitch Grassi, Kevin Olusola, and Avi Kaplan. This quintet formed in 2011 after an open online audition arranged by their manager, Ben Fagan. Hoying provided baritone and leadership, Maldonado and Grassi sang lead and tenor, Olusola contributed beatbox and tenor vocals, and Kaplan handled bass and vocal arrangements. Their a cappella arrangement of Radiohead’s "Creep" in 2011 quickly went viral, establishing the group’s signature sound. Below is a verified snapshot of each founding member’s role, background, and contribution to the group’s early identity.

How the Original Pentatonix Lineup Came Together

The group formed in June 2011 when manager Ben Fagan invited five a cappella enthusiasts to audition online. Hoying, Maldonado, and Grassi already performed together regionally; Olusola joined as a classically trained cellist who beatboxed; Kaplan completed the bass role. Their winning arrangement of "Creep" in September 2011 launched their YouTube channel and defined the vocal blend that carried through their first albums. Each member brought complementary skills: tight harmonies, rhythmic ingenuity, and genre-spanning arrangements that made a cappella mainstream again.

Key Contributions of the Founding Five

  • Scott Hoying: Musical direction, baritone harmonies, and leadership; background in collegiate groups like SoCal VoCals
  • Kirstin Maldonado: Bright soprano lead and lyrical clarity; studied at University of North Texas
  • Mitch Grassi: High tenor and countertenor; meticulous tuning and arranging
  • Kevin Olusola: Beatbox foundations and percussive vocals; cello expertise adding classical depth
  • Avi Kaplan: Richer bass tones and vocal arranging; jazz and pop influences that shaped early repertoire

Musical Roles and Vocal Arrangements in Early Years

In the original lineup, vocal responsibilities were distributed to maximize each singer's range and strengths. Hoying often sang baritone or arranged parts, Maldonado carried high harmonies and lead melodies, and Grassi provided countertenor color. Olusola’s beatboxing gave the group percussive texture, while Kaplan anchored songs with bass lines and internal vocal arrangements. This balance allowed Pentatonix to recreate complex songs a cappella with precision and dynamics that rivaled full bands.

Changes After the Founding Era

In 2017, Avi Kaplan left the group, transitioning Pentatonix to a quartet. They later added Matt Sallee as bass, maintaining five-part harmony while evolving their sound. Despite lineup shifts, the original five remain the group's foundation: the moment the initial blend clicked, the viral breakthrough, and the decisions that turned an online experiment into a sustained, award-winning act. Understanding the original members of Pentatonix clarifies how their chemistry and complementary skills set the course for everything that followed.
