Pó de Mico. João Teixeira Guimarães (1883-1947) By Estelle Bertrand. João Teixeira Guimarães, better known as João Pernambuco, played a leading role in the development of the Brazilian guitar. The latter also had a significant influence on the musical production of his compatriot Heitor VillaLobos, particularly in his Brazilian Popular Suite. He is notably responsible for many chôros, the best known of which are Sons de Carrilhoes, Interrogando, Jongo and Dengoso. Pó de Mico is a jovial piece in G major, with frequent borrowings from relative tones and harmonies that flirt with jazz. Rhythmically, the recurring cell "sixteenth note-sixteenth note" is one of the typical stylistic elements of the chôro. In the manner of a refrain, the initial sixteen measures are replayed several times and come to structure the structural development which follows the ABACA form. Be vigilant for the regularity of the discourse in the passages based on scales and arpeggios.
