Beethoven sonatas are great to develop technique and phrasing. I find Bach difficult to understand and enjoy, so I avoid it. The Bach inventions are not good if you are "looking for sudies that have much more to them than mechanical difficulty". Of course, you should do them if you wish to develop the ability to play multiple voices, but other than that, there is music out there more fun. Try the easier Liszt Transcendental etudes, like No.3,7, or 9. Right now, I am playing Liszt's Totentanz for solo piano as a series of exercises, or at least, that is how I percieve it.donjuan
I am a faily advanced pianist, I can play some pieces Rachmaninov, Chopin and Liszt. Though I practice technical exercises, scales, arpeggios and broken chords, I have never learned any studies. I have considered starting on the Chopin Opus 10 studies, but I'm not sure if that would be a good place to start. I have also considered learning the Bach Two Part Inventions as studies, I read somewhere that his 15 pieces were written for the purpose of teaching. I suppose I am looking for studies that have much more to them than mechanical difficulty, and that are not astronomically difficult to play. Any suggestions please?
