Although Soler wrote for the church it is his secular compositions, in particular his keyboard sonatas, that are his best-known achievement. Most were written for Don Gabriel, son of King Carlos III, and they show how adeptly Soler had absorbed the influence of Domenico Scarlatti but also listened to the changing musical styles emanating from Vienna. The result is music of brilliance, full of unexpected modulations, rapid figuration, and graceful charm. This is volume 4 of the complete Soler Keyboard Sonatas.
