Egberto Amin Gismonti (born December 5, 1947) is a Brazilian composer, guitarist and pianist.

Gismonti was born in the small city of Carmo, state of Rio de Janeiro, Brazil, into a musical family. His mother was from Sicily and his father was from Beirut, Lebanon. At the age of six, he started studying the piano at the Brazilian Conservatory of Music. After studying the classical repertoire in Brazil for fifteen years, he went to Paris, France, to delve into modern music. He studied with Nadia Boulanger (1887–1979), after acceptance as a student by the composer Jean Barraqué,a student of Anton Webern and Schoenberg. Boulanger encouraged Gismonti to write the collective Brazilian experience into his music.

Gismonti is a self-taught guitarist. After returning to Brazil, he designed guitars with more than six strings, expanding the possibilities of the instrument. Approaching the fretboard as if it were a keyboard, Gismonti gives the impression that there is more than a single guitar player. Gismonti’s sojourn in the Xingu region of the Amazon basin made a lasting impression. This is documented musically in tunes like “Yualapeti” and “Sapain” (Yualapeti shaman, Sapain) and in the recordings Dança das Cabeças (Dance of the Heads, 1977), Sol do Meio-Dia (Noon Sun, 1978), which he dedicated to the Xingu, and Duas Vozes (Two Voices, 1984).
