The style can be adapted to almost any tune, all it needs is a melody that is easy to harmonize and four men ready to sing. Other features in the barbershop style are the use of minor and seventh chords, repeated phrases and a rolling chord called a bell chords. These are used to add musical flavor to the tune complimenting the acapella experience of four part harmony.
You will hear Harmonium singing Swing, love songs, Gospel and Hymns, even a polka tune along with songs traditionally associated with Barbershop. Songs like Lida Rose, Wait 'Til the Sun Shines Nellie, Coney Island Baby and many other old favorites.
