Description: The Banjo Ukulele, banjo uke or banjolele is a four-stringed musical instrument with a small banjo-type body and a fretted ukulele neck. “Banjolele”, sometimes also spelled “banjelele” or “banjulele”, is a generic nickname [clarification needed] given to the instrument. The earliest known Banjo-Ukuleles were built by John A. Bolander and by Alvin D. Keech, both in 1917.
History: The banjo-ukulele gained popularity during the 1920s 1930s. Combining both the ukulele and the banjo, hence its name. The development was further pushed by the need a vaudeville performers to have an instrument that can be played with the ease of a ukulele.
