- The first etude op 25 of Chopin, for me seemed to be difficult and when I looked on the sheet it was quite easy to play (musicality is an other challenge)
- You can have a look on some of the preludes of Scriabin too (Op. 17 n°3 for example)
- Also on the Sospiro of Liszt, there is several difficulties but if you have a bit of experience it's totaly approchable
- The first piece on the "Harmonies poétiques et religieuses", "Invocation" of Liszt too
- Humm, that's it, there is certainly a lot of other pieces i'm not thinking about but it's late in Belgium so my mind is deep in the mist...
