Across of Carnegie Hall, this store is the mecca of classical music sheet music, long known to classical musicians for being the source to find nearly any written source of classical work you could think of. There are thousands of books here, arranged by your instrument, as well as biographies, histories, and a research department upstairs. Are you looking for a Crumb score? Are you looking for the Goldberg Variations but you don't like the lighter pages of the Schirmer and prefer the clarity, generous spacing, and heft of the Verlag edition? You can afford to be exactly this picky at Patelson's. I know of nowhere else in America with such an expansive collection of classical music to browse. Yet another unique and amazing thing about living in New York. There's a reason this place is just as much an institution as it's more glorious neighbor across the street.
