Banjo uke

The banjolele (brand name; sometimes banjo ukulele or banjo uke) 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 given to the instrument, which was derived from the "banjulele-banjo", introduced by Alvin D. Keech in 1917.
