Sor’s sonata in C, now known as op. 15(b), consists of a single movement, an allegretto. It is an uncompromising work, developing its ideas to the full and concentrating on musical values rather than on what the guitar can easily do. Like the first sonata [op. 14], it was published in 1810 or shortly before and therefore dates from Sor’s Spanish period.
