The editor has chosen 40 keyboard sonatas from the more than 500 written by Domenico Scarlatti. These serve as a progressive initiation into Scarlatti's keyboard artistry.
This is a selection of 40 of Scarlatti's Sonatas put together by Marthe Morhange Motchange who was a professor of piano in Paris. The book has an introduction, a forward, a ``thematic table'' which gives the first few bars of each sonata and K or L number, and a table of ornaments before getting to the music.
