 While fado remains at the core of his music, do Carmo has used Frank Sinatra-style and French-style pop balladry and Brazilian bossa nova to give his music its distinct flavor.His uniqueness, apart from the special timbre of his voice, is in his ability to bring composers from other styles such as jazz.This is mainly seen in his success "Um Homem na Cidade", which although now known as a fado classic, has an obvious jazz chord progression.
