formsons

Formsons are a type of musical ensemble that originated in the United States during the 1920s and 1930s. The term "formsons" is a portmanteau of "form" and "sons," reflecting the group's focus on traditional American folk music and their use of a specific vocal arrangement. This arrangement typically consists of three or four male vocalists who harmonize in a close, three-part or four-part harmony, often using a technique called "close harmony" or "close singing."

The formsons' sound is characterized by its simplicity and austerity, with a strong emphasis on vocal melody and harmony. The groups often perform a cappella, without instrumental accompaniment, and their repertoire includes a wide range of traditional folk songs, spirituals, and work songs. Some notable formsons include the Carolina Chocolate Drops, the Clancy Brothers, and the Dillards.

Formsons gained popularity during the folk music revival of the 1950s and 1960s, as audiences sought out authentic, unadorned performances of American folk music. The groups' performances often featured a sense of camaraderie and community, with the vocalists working closely together to create a unified sound. Today, formsons continue to perform and record, keeping the tradition of American folk music alive.
