Have you ever wondered how music has evolved over the years? One YouTube video tries to answer that question by distilling 10 centuries of song into four-and-a-half minutes.
A quintet of singers, collectively called Pentatonix, start off with a haunting chant from the 11th century. They then move on to Pachelbel’s Canon from the 1600s, followed by Beethoven’s Symphony No. 5 from the 1800s. The group eventually sings its way into the 20th century and finally the present day, which features hits from Justin Bieber, Rihanna and Carly Rae Jepsen.
