Gentlemen's Agreement (quartet)
A Gentlemen's Agreement is a type of barbershop quartet, a musical ensemble consisting of four male voices singing a cappella harmony. Specifically, the term often implies a quartet that maintains a particular aesthetic, commonly characterized by a sophisticated and often humorous stage presence, precise vocal blend, and a commitment to performing both traditional and contemporary barbershop arrangements. The name suggests a mutual understanding between the members to uphold certain performance standards and maintain a professional image. While any barbershop quartet can technically be described as such, the term often alludes to quartets recognized within the Barbershop Harmony Society (BHS) for their high musical and performance quality. These groups often compete at district and international levels within the BHS.
