Conlon Nancarrow: A Chronology: "1947: Money left by his father becomes available to Nancarrow; he uses it to return to New York City and buy a player piano; in New York, has a punching machine made to punch player-piano rolls; hears John Cage perform Sonatas and Interludes

1948: Returns to Mexico and marries Annette Margolis, painter and assistant to Diego Rivera; they move to land she owns on the outskirts of Mexico City and build a house (land that Nancarrow lives on to this day); Nancarrow begins writing his Studies for Player Piano, beginning with what will become No. 3 "
