BarbershopBarbershop is a style of A cappella harmonized singing consisting of four vocal elements: the 'lead' (2nd tenor), the 1st tenor, the baritone, and the bass. These are often arranged into quartets, but entire Barbershop choruses also perform. This style features an easily discernable melody, with each singer adjusting within their register to create balanced, symmetrical chords in major and minor scales. Barbershop groups can perform any style of music once it has been arranged for it, but there is a set of 'traditional standards' that comprise their primary repertoire. Examples of these would be 'Sweet Adeline' and 'Alexander's Ragtime Band'. The performance aspect usually also includes a recognizable Vaudevillian type garb, simple step routines, and the use of accessories like a hat or cane for embellishment.
