Antonio Soler (1729-83) was a monk of Monasterio de San Lorenzo de El Escorial and also the choir master. He composed much church music, mainly for choir, and for the Royal Court, because El Escorial was also a Royal Palace. Some Masses, two Miseseres, quintets for organ and strings, duets for organs, are his main works.

Soler is estimated to have composed more than 200 keyboard sonatas, of which about 120 plus are known; six quintets for strings and keyboard; a considerable number of liturgical compositions; a number of villancicos; six conciertos for two organs (or other keyboard instruments).
