Musical scholars like Ralph Kirkpatrick, whose classic book on Scarlatti is here quoted at length (though without acknowledging the source), are understandably fascinated by the inexhaustible diversity brought to basically binary-form movements by this Sicilian-descended, Neapolitan-born genius, who spent exactly half his life in the Iberian peninsula. For music lovers in general, however, the fascination lies in his enormous vitality, his demands for unprecedented keyboard virtuosity and his highly individual use of melodic, harmonic, rhythmic and instrumental Hispanicisms that demonstrate how far he had fallen under the spell of Spanish folk-music and folk life.

All these facets are zestfully displayed on this stimulating disc. Apart from genuine Spanish dances—the bulerias of Kk492, the peteneras of 502 and the Andalusian 519 which bubbles from minor to major—there are impressions of street processions (490, 491 with unmistakable sounds of trumpets, horns and drums, and a marching element in 518) and the exciting rattle of castanets or tambourines in the rapid note-reiterations of 141, 119 and 455, and Scarlatti's unique telescoped chords (490 and the even more dissonant 119). His unexpected modulations and side-stepping key-changes are to be heard in several sonatas, and his stamping basses in 502 and 517. And besides the hurtling arpeggios or broken-chord patterns (141, 454) and chains of trills (118, 501) there are the Scarlattian quirks such as the out-of-step octave unisons in 203 or the surprise changes of metre in 502. It is a pity we can't see Staier performing the vertiginous cross-hand leaps in the remarkable 108, as well as in 118 and the exuberant 119, but the sheer breakneck speed at which he plays 517, shooting off like an arrow from a bow, will leave listeners breathless.

He uses a harpsichord of German type with the G in alt called for in 454, 455 and 502, makes a few logically defensible registration changes in some sonatas, and adds occasional discreet ornamentation on repeats (which are fully observed except in five cases). This is a most enjoyable disc, which I would recommend very highly: there are many recordings of Scarlatti, but this is among the best.
