Eighty five kilometers to the north-west of Moscow, in Klin and its environs, in Maidanovo and Frolovskoye estates, Tchaikovsky spent the last eight and a half years of his life. During those extremely successful years the operas "Charodeika", "Cherevichki", "Iolanta" were created, "The Queen of Spades" was orchestrated, ballets "The Sleeping Beauty" and "The Nutcracker", symphonies "Manfred", No 5 and No 6, romances, piano and orchestra compositions were written. On May 5, 1892, PI Tchaikovsky settled in the house in the outskirts of Klin and lived his last seventeen months there. In this quiet corner he found ideal conditions for his work: here he completed the scores of "Iolanta" and "The Nutcracker", wrote 18 piano pieces, 72 compositions, "The Night" vocal quartet, romances, composition No 23 to the poem of D. Ratgauz, Third piano concert which was his last composition. The manuscript is dated "October, 1893. Klin." In this house Tchaikovsky wrote Symphony No 6 which he considered his "best and most elaborated composition". And it was from this house that he left for his last concert trip to St. Petersburg on October 7, 1893. In 1894, the first Russian memorial music museum was opened in the Klin house.
