Sor’s 24 very easy exercises op. 35 were first published in Paris in 1828. The original title was Vingt quatre exercices très faciles et soigneusement doigtés (24 very easy exercises, carefully fingered).
With his 24 progressive lessons op. 31, Sor had already composed instructional pieces which were a good deal easier than his previous studies in op. 6 and op. 29. He had given the title “Lessons” to those easier pieces of op. 31. However, it seems that these were not easy enough, for a preface to op. 35 says that certain people had said to him that they required too rapid a progress and aimed too high. Therefore he composed his op. 35, a set of extraordinarily easy pieces for beginners, which he called not studies, and not lessons, but “Exercises”. See the notes to op. 31.
The exercises op. 35 no. 5 and op. 35 no. 22 are FREE TO EVERYBODY.
