Fernando Sor was not only one of the great guitarists of his era but a major composer for the instrument, described by a contemporary critic as "the Beethoven of the guitar". His desire for the guitar to represent a miniature orchestra in timbre is a distinctive feature of his many compositions. The 24 Progressive Lessons, Op. 31 offer a panoramic lexicon for the student, moving from a simple waltz to perpetual motion, whilst the charming Six Little Pieces, Op. 32 further explore technical efficiency and musical expressiveness.
