Well it's a cheap, well paged book for pianists and has 4 of the most beautifull pieces of piano literature.(PLAY ALL OF THEM !!!!). I prefered this edition because the other one that has both 2 series of improptus and some other pieces (Alfred again) is too much money and you get nothing more than this one here.(Except the improptu op 142,no 2 that is in the other set).
Nothing special about this sheet music - the typical (good quality) print. Song is for intermediate to advanced pianists. I have several large books of classical music, and this song is not in any of them. I ordered the sheet music because it is a fantastic song and a must have for any pianist's repertoire.
