Antonio Soler composed more than 500 sacred choral musical pieces in his native Spain. Today, though, it is his 200-or-so keyboard sonatas that are arousing the curiosity of performers. Our anthology volume presents 18 of them from all periods of the composer’s creative life. In 1761 Soler wrote a music-theory treatise in which he sketched out methods of quickly modulting to remote keys; these techniques are also found in his keyboard sonatas. In this Urtext volume the player will enjoy the subtlety and speed of modulation between keys, and a brilliant lightness occasionally darkened by moments of pathos.
