Yesterday I received an Amazon shipment that included piano books collecting pieces by Debussy and Satie. When these were added to my collection, I felt fairly satisfied with my holdings in terms of “hitting the bases.” Along with those two, I have a book of Beethoven sonatas, a Chopin anthology, Bach’s Well-Tempered Clavier, Gershwin’s preludes, the Peanuts theme, and a couple miscellaneous anthologies. What should be the next addition to give me access to a well-rounded selection of piano repertoire? Shostakovich’s Preludes and Fugues strike me as an attractive option, as do Schubert’s piano sonatas. But what do you think?
