Alfredo da Rocha Viana Filho, known as Pixinguinha was a Brazilian composer, arranger, flutist and saxophonist born in Rio de Janeiro. Pixinguinha composed popular music, particularly within the genre known as choro, including some of the best-known works in the genre such as "Carinhoso", "Glória", "Lamento" and "Um a Zero".
By integrating the music of the older choro composers of the 19th century with contemporary jazz-like harmonies, Afro-Brazilian rhythms, and sophisticated arrangements, he introduced choro to a new audience and helped to popularize it as a uniquely Brazilian genre. He was also one of the first Brazilian musicians and composers to take advantage of radio broadcasting technology and studio recording.
