Woodshedding is three individual voices tenor bari and bass creating barbershop harmonies by ear to a leads melody without any written arrangement. The melody is introduced by the lead so all can become familiar with it but should not have a wellknown arrangement This art hearkens back to over a century ago to the origins of barbershop quartet singing where four men would gather frequently at the local barber shop and harmonize to the familiar tunes of the day.
