Chopin wrote to T. Woychiechowski on 15 May 1830: "The Adagio from my new concerto is more romance-like, calm, melancholic and might create the impression of a kind glance at a place which has left a thousand dear memories in one's mind."

James Huneker: "The C sharp minor part is imperious in its beauty, while the murmuring mystery of the close mounts to the imagination."
