hi people! my teacher ask me to choose a study from clementi's gradus ad parnassum, but none keeps my attention in particular.
If you haven't learned all of them yet, some of his sonatas are late intermediate/early advanced, such as op. 7, op 13, and I think op. 40/50.
Well... when you think about it... what isn't a study? Everything you play can be considered as such. Whether it be from an exercise book or from a book of pieces by X composer, anything you play can be thought of that way. It's your choice. Use an exercise book, or learn another piece of repertoire, not to mention something that actually sounds like music.
[burgmuller's] Op. 100 and the Inventions/Sinfonias are actual pieces of music.
