Sor’s Deux thèmes variés et douze menuets op. 11 are something of a miscellaneous collection and first appeared in Paris in 1822 or shortly before.
The twelve minuets are in an unusual style, with their abrupt changes of register, their sudden running passages, and their scordaturas. They are among the finest of Sor’s miniatures and have deservedly kept their popularity over many years. Some are certainly from Sor’s Spanish period, and it is quite possible that they all are: see Chapter 1 of my book Fernando Sor, Composer and Guitarist.
The theme of the first set of variations is almost the same as that of a “Thème varié” which Meissonnier published separately with a different arrangement of variations and to which he gave the numbering op. 15 (it is 15c in this edition). Minuet no. 12 was also published as op. 13 no. 4.
You can hear minuet no. 6 played by Paul Bizot here.
