After Fantaisie Élégiaque op. 59, perhaps the most magnificent work for solo guitar Sor ever wrote, he published only one work for solo guitar: Introduction à l'Etude de la Guitar 25 leçons progressives, Op. 60. This was a set of easy pieces where he was finally able to successfully write guitar music for beginners while still maintaining his uncompromising respect to the art of proper voice leading. His previous sets of “easy pieces” were criticized during his own time in Paris for being too difficult for beginners and everyone who has taught the guitar knows that a student must be quite advanced to approach Sor's beautiful Lessons, Exercises and Etudes.
