Pentatonix (often abbreviated as
PTX) is an American
a cappella group consisting of five
vocalists originating from
Arlington, Texas. The members in this group are Avi Kaplan, Scott Hoying, Kirstin Maldonado,
Kevin Olusola, and Mitch Grassi. Their work, which is mostly in the
pop style, consists of covers of existing songs, sometimes in the form of
medleys, along with original material. Their music is defined by their own
arrangement style, tight vocal harmonies, extensive vocal riffing, deep and steady
vocal basslines, and a diverse range of
vocal percussion and
beatboxing.
