Reconciling European tradition and Brazilian influences was also an element that bore fruit more formally later. His earliest published work "Pequena suíte" for 'cello and piano of 1913 shows a love for the 'cello, but is not notably Brazilian, although it contains elements that were to resurface later. His three-movement "Suíte graciosa" of 1915 (expanded to six movements c. 1947 to become his String Quartet No. 1) is influenced by European opera, while "Três danças características (africanas e indígenas)" of 191416 for piano, later arranged for octet and subsequently orchestrated, is radically influenced by the tribal music of the Caripunas Indians of Mato Grosso.
