Electric mandolin 4-string version. A related instrument, the Bahian guitar, was developed in Brazil beginning in the 1940s. Bahian guitars typically have a solid body and 4 or 5 single-course strings tuned in fifths, but are considered to be electric versions of the cavaquinho rather than the mandolin. Both four string single course and eight string double course solid body mandolins have been produced by several makers, as well as five string single course models. From 1956 to 1976, Fender produced a four string version which they simply called the "Fender Electric Mandolin". Its body shape was based on a smaller version
Mandolin instruments. The mandolin and guitar were played in both classical music and pop music. Although used in popular music, both instruments were also taught in the Saigon National Conservatory (now the Conservatory of Ho Chi Minh City). However, the mandolin has disappeared from the conservatory where it had been taught, apparently dropped from the curriculum. Instead of Guitar-Mandolin department, the school lists Guitar-Accordion. Though probably never a dominant instrument, the mandolin was learned by enough people to have a presence among the settlers who left Vietnam for the United States, and who continued to play mandolins in their new home.
