Sor’s fantasia [op. 12] was first published in London in 1815 or shortly after. A fine extended work, it is in fact a set of variations and is an elaboration of the simpler set on the same theme which is today known as op. 3 and which dates from Sor’s Spanish period. Sor has added an introduction, coda, and three new variations. The new work is dedicated to Friedrich Kalkbrenner, the famous pianist who lived in London from 1814 to 1823, that is exactly the same period as Sor. Variation 7 is a fine example of the ancient guitar and lute technique of campanelas.
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.
