You want Vol. 813. Not this one...
Oof. Pay attention. This is not Czerny's version. Wm Mason mangles the text by WRITING IN editorial ornaments and embellishments. This version is fine only if:
1. You are taking piano lessons in the 1890s when historical performance practice was ignored.
2. You are breaking a student down before they are allowed to play Beethoven Chopin Brahms etc.
Buyer beware. You want the Czerny Bach Inventions only two bucks more. Or perhaps the urtext only $30 more...
