Scott Hoying has got nothing against barbershop quartets and doo-wop singers.
They're great, he says, if you like those styles of music.
But Hoying, an Arlington native who heads up a five-member a cappella group called Pentatonix, prefers to create an a cappella sound that's a bit more "contemporary" and "innovative."
His philosophy is clearly in sync with the producers of NBC's The Sing-Off.
Pentatonix is one of 16 a cappella groups chosen to compete in the vocals-only TV talent show, which begins its third season at 7 p.m. Monday.
"A lot of a cappella is very doo-woppy and kind of barbershop-sequel," Hoying says. "But our group has brought in the influence of dance music. We have a lot of cool sounds and cool effects that we sing that makes us sound more like techno music.
"It's never been done before in the a cappella scene, and I think it's what got us on the show."
