The most subscribers for an a cappella group on YouTube is 20.5 million, achieved by Pentatonix (or PTX) (USA), as of 11 April 2025.
Since there are five band members, the quintet decided to name themselves 'Pentatonix' after the Pentatonic Scale, as it has five notes per octave. Pentatonix has also won three Grammy Awards, including two for 'Best Arrangement, Instrumental or A Cappella' and one for 'Best Country Duo/Group Performance'.
