L.V. Beethoven Piano Sonatas Vol. 1
Ed. Breitkopf (Krebs), Kalmus Reprint (Public Domain)
Restored Sheet Music. (Staves straightened, misprints corrected). No fingerings. This Edition is also called "The American Urtext".
"I think the best Beethoven interpretation comes from using the Kalmus Edition,- the Urtext Edition-, and playing what Beethoven asked. You are sure then to be on the truth. (Robert Casadesus)
"Kalmus (Reprint from Breitkopf) and Henle Urtext Editions are the best" (Claudio Arrau).
