Later years

From the 1960s onward, Copland turned increasingly to conducting. Though not enamored with the prospect, he found himself without new ideas for composition, saying, "It was exactly as if someone had simply turned off a faucet." He became a frequent guest conductor in the United States and the United Kingdom and made a series of recordings of his music, primarily for Columbia Records. In 1960, RCA Victor released Copland's recordings with the Boston Symphony Orchestra of the orchestral suites from Appalachian Spring and The Tender Land; these recordings were later reissued on CD, as were most of Copland's Columbia recordings (by Sony).

From 1960 until his death, Copland resided at Cortlandt Manor, New York. Known as Rock Hill, his home was added to the National Register of Historic Places in 2003 and further designated a National Historic Landmark in 2008. Copland's health deteriorated through the 1980s, and he died of Alzheimer's disease and respiratory failure on December 2, 1990, in North Tarrytown, New York (now Sleepy Hollow).

Following his death, his ashes were scattered over the Tanglewood Music Center near Lenox, Massachusetts. Much of his large estate was bequeathed to the creation of the Aaron Copland Fund for Composers, which bestows over $600,000 per year to performing groups.
