The Rajão is probably the most peculiar instrument of all the hand strings played on the island.

It is a 5-stringed instrument, with a sui generis tuning, in which the lowest string is the third, a typical feature of the 17th-century hand guitars, and is used to accompany singing and folk dancing.

Due to the presence of the Madeiran community in Hawaii, the Rajão is one of the ancestral instruments that influenced the creation of the Ukulele, with 4 strings and smaller dimensions.
