These include “Reglas generales para acompañar órgano, clavicordio o arpa” (Madrid, 1702) [a work covering accompaniment techniques for organ, clavichord and harp] and a book of masses dedicated to Philip V of Spain.
A large number of compositions by Torres are preserved in the archive of Guatemala Cathedral, although some of these are in poor condition with some missing parts.
These compositions include a large number of villancicos in three, four, seven and eight parts, solo cantatas for treble, soprano and “contralto”, an 8-part “Missa annuntiate nobis” with violin, oboe and basso continuo accompaniment and a 4-part a cappella mass "ad omnem tonum" concluding in an eight-part Agnus Dei based on Magnificat tones.
The solo soprano cantata Afectos amantes contains an aria "La solfa mia" based on the natural hexachord which may be a personal statement by Torres of his approach to composition.
