A cavaquinho player is called a cavaquista.
There are several forms of cavaquinho used in different regions and for different styles of music. Separate varieties are named for Portugal, Braga (braguajina), Minho (minhoto), Lisbon, Madeira, Brazil, and Cape-Verde; other forms are the braguinha, 'cavacolele', cavaco, machete, and ukulele.
The word "cavaquinho" alone usually refers to the Portuguese cavaquinho.
The Venezuelan concert cuatro is very nearly the same instrument, but somewhat larger.
The Brazilian cavaquinho is slightly larger than the Portuguese cavaquinho, resembling a small classical guitar. Its neck is raised above the level of the sound box, and the sound hole is usually round, like cavaquinhos from Lisbon and Madeira.
The cavaco is a smaller version of the Brazilian cavaquinho, similar in size to the Portuguese cavaquinho. It is part of a samba ensemble (see the international section, below). The name cavaco means "wood splinter" in Portuguese – probably back-formed from the original name cavaquinho ("little wood splinter").
The minhoto cavaquinho, associated with the Minho region in Portugal is similar to the viola braguesa. Its neck is on the same level as the body. Like the braguesa, the minhoto's sound hole was traditionally shaped like a stylized ray (fish); the shape is called "raia" in Portuguese.
The standard tuning in Brazil is D G B D.
Other tunings include:
Different forms of cavaquinho have been adapted in different regions. Varieties used outside of Iberia are found in Brazil, Cape-Verde, and Madeira. The locally iconic Caribbean region cuatro family and the Hawaiian ukuleles were both adapted from the cavaquinho.
The samba cavaco is played with a pick, with sophisticated percussive strumming beats that connect the rhythm and harmony by playing the rhythm "comping". Some of the most important players and composers of the Brazilian instrument are Waldir Azevedo, Paulinho da Viola, and Mauro Diniz.
In Cape Verde the cavaquinho was introduced in the 1930s from Brazil. The present-day Cape-Verdean cavaquinho is very similar to the Brazilian one in dimensions and tuning. It is generally used as a rhythmic instrument in Cape-Verdean music genres (such as morna, coladeira, mazurka) but it is occasionally used as a melodic instrument.
The ukulele is an iconic element of Hawaiian popular music, which spread to the continental United States in the early 20th century. It was developed from the braguinha and rajão, brought to Hawaii in the late 19th century by Portuguese immigrants from Madeira Island.
The cuatro is a family of larger 4-stringed instruments derived from the cavaquinho that are popular in Latin-American countries in and around the Caribbean. Versions of the iconic Venezuelan cuatro are very similar to the Brazilian cavaquinho, with a neck like a Portuguese cavaquinho.

Sampaio explains Minho region's archaic and Hellenistic modes by possible survival of Greek influences on the ancient Gallaeci of the region, and stresses the link between this instrument and historical Hellenistic tetrachords.
