I you tubed four Scarlatti sonatas and blogged about them as per challenges, crossed hands, trills..so they are embedded at my blog site, which is growing to a point, I can't easily reference them separately.
But on You Tube I can find them quickly and send a link as with K. 159
I recorded 28 essercizi on two CD albums.
The others are the A Major, K. 113
the G Major, K. ?
and E Major, K. 380
