An analysis of his repertoire reveals a wide range of interests. It spanned all the idioms of Brazilian popular music of the 20th century: samba, bossa nova, Afro-bahian ritual music, frevo, choro, and North Eastern Sertão music, and even European and Japanese lullabies. Like most musicians growing up in the 1940s and 1950s, he was deeply influenced by jazz, especially bebop and swing. He covered Thelonious Monk's "Round Midnight" on two recordings, and Jerome Kern's "All the Things You Are" on three occasions (including his first solo album).
