The shanty genre was typified by flexible lyrical forms, which in practice provided for much improvisation and the ability to lengthen or shorten a song to match the circumstances. Its hallmark was call and response, performed between a soloist and the rest of the workers in chorus. The leader, called the "shantyman", was appreciated for his piquant language, lyrical wit, and strong voice. Shanties were sung without instrumental accompaniment and, historically speaking, they were only sung in work-based rather than entertainment-oriented contexts. Although most prominent in English, shanties have been created in or translated into other European languages.
