Fernando Sor (baptised 14 February 1778 – 10 July 1839) was a Spanish classical guitarist and composer of the late Classical era and early Romantic era. Best known for writing solo classical guitar music, he also composed an opera (at the age of 19), three symphonies, guitar duos, piano music, songs, a Mass, and at least two successful ballets: Cinderella, which received over one hundred performances, and Hercule et Omphale.
Sor was a prolific and, in his time, quite popular composer. There was a great demand for him to compose material that was approachable by less accomplished players. The resulting body of instructional studies he produced is not only noteworthy for its value to students of the guitar, but for its inherent musicality.
Partly because Sor was himself such a classical guitar virtuoso—contemporaries considered him to be the best in the world – he made a point of writing didactic music for players of that instrument of all levels. His Twelve Studies Op. 6, the Twelve Studies Op. 29, the (24) Progressive Lessons Op. 31, and the (24) Very Easy Exercises Op. 35 have been widely played for two hundred years and are regularly reprinted. On the other hand, Sor’s concert pieces, like the popular Introduction and Variations on Mozart’s “Das klinget so herrlich” Op. 9, belong to the advanced guitar performance repertoire.
Unlike modern classical guitar players, Sor used the smaller, slimmer “Romantic” guitars predating. He used the ring finger of his plucking hand “rarely” and “only for harmony (never for melody).” He eschewed the use of nails on that hand.
Selection of Pieces for Inclusion in this Book
I played many pieces by Fernando Sor as a student of the classical guitar and still perform them today. So, I searched my music books, anthologies, collections and recordings to identify the best pieces used for teaching, yet are still enjoyable as miniatures on their own. Of course, most technical studies were eliminated but there were many pieces to include and I arranged some of these for ukulele.
These are the results. Enjoy!
