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.
Check out the video's full list of songs, here.
