The Chorus of DuPage represents the DuPage Valley Chapter of the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America, also known as the Barbershop Harmony Society.

The Barbershop Harmony Society, the world's largest all-male singing society, brings together men of all ages who love singing music in the barbershop style — four-part, A Cappella (unaccompanied), close-harmony singing.

In barbershop, the melody of the song is carried by the lead singer, while the tenor harmonizes above the melody. The bass sings the lowest notes and the baritone fills in the missing notes below or above the melody to complete the chorus.
