Heitor Villa-Lobos once confessed that he loved to write string quartets, stating ‘one could say that it is a mania’. His 17 quartets form a substantial part of his chamber music output, covering a long career that embraced national pride and musical experimentation leading to the rarefied atmosphere of the final masterpieces. Often drawing on the musical folklore of Brazil, these quartets are an outpouring of spontaneous and daring invention. Ranging from austere polyphony to compelling expressiveness and virtuosity, they represent one of the most distinctive bodies of chamber works in 20th-century music.
