The compositions by the greatest Brazilian tango composer and pianist Ernesto Júlio de Nazareth (1863 -1934) are strongly influenced by Brazilian folk music. He preferred light entertainment, and his dance music has remained extremely popular in his home country until today. Heitor Villa-Lobos called him 'the true embodiment of the Brazilian soul'. Nazareth composed primarily choros music which is very common in Brazil, but it was his 25 tangos (25 Tangos Brasileiros for piano) that made him famous.

The melancholy waltz Confidencias in A minor (already published for piano in Valsas brasileiros) bridges the gap between Latin American folkore and Romantic elements, as can be found in the waltzes by Chopin. The work's specific expressive chromaticism in melody and harmony stands out particularly in the arrangement for chamber music ensemble.
