In December I've posted a download link of a single pdf file with the complete sheet music the keyboard sonatas by Scarlatti. Unfortunately in the process of optimization of the file, the type font setting of 7 sonatas been corrupted. I've replaced these sonatas (K.142, K.143, K.144, K204a, K.204b, K452, K.453).
Furthermore, I've added a sonata which is not included in the Kirkpatrick catalogue: the sonata in A Major, Cary 703 fol.64v/46.
See for more details:
So, this updated pdf file (Scarlatti-Sonatas_K1.-K.555+.pdf, 2256 pages) now contains 557 keyboard sonatas of Domenico Scarlatti. Each sonata is bookmarked in order to jump quickly to the beginning of a specific sonata.
I don't know if there is any CD recording available of the A Major-sonata (Cary 703). Therefore I've included a midi version (Scarlatti-Sonata_A_Major_Cary_703.mid).
A zip file with pdf and midi files can be downloaded here: http://www10.zippyshare.com/v/MDQrI4v7/file.html
