Also called machimbo, machim, machete (in the Portuguese Atlantic islands), manchete or marchete, braguinha or braguinho, or cavaco and ukulele (in Hawaii). A cavaquinho player is called a cavaquista.
The most common tuning is D-G-B-D (from lower to higher pitches); other tunings include D-A-B-E (Portuguese ancient tuning, made popular by Júlio Pereira) and G-G-B-D and A-A-C#-E. Guitarists often use D-G-B-E tuning to emulate the highest four strings of the guitar. The G-C-E-A tuning is sometimes used to emulate the soprano/tenor ukulele, an instrument developed from the cavaquinhos brought to Hawai'i by Portuguese immigrants in the late 19th century.
