Adagio cantabile The Adagio movement opens with a famous cantabile ("in a singing style") melody. This theme is played three times, separated by two modulating episodes: the first episode moves from F minor to E-flat major , and the second from A-fl to E major . With the final return of the main theme, the accompaniment becomes richer and takes on the triplet rhythm of the second episode. There is a brief coda. From Wiki
