Sor’s fantasia op. 10 was first published in Paris in about 1817-22, at a time when Sor was living in London. A slow introduction leads into a melodious theme, followed by two variations; then a section called “Majeur” which is rather an interlude than a true variation; then two more variations and a coda conclude this fine extended work.
This edition comes from the new 2019 second edition of Sor’s New Complete Works for Guitar edited by Brian Jeffery. The Introduction and Index to the entire series can be seen here on this site.
