Sor’s Fantasia [op. 7] was first published when Sor was in Paris in 1814 and probably composed there. It is undoubtedly a virtuoso work, a major piece from a time when he was at the height of his powers.
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.
