I started learning to play classical piano 6 months ago, at 27 years of age. Although I did not play the piano at all prior to this, I have been listening to classical piano and attending concerts for several years.
In these six months, I have made some progress, and in particular can now play the Chopin E-minor prelude (Op. 28 No. 4) and a Clementi sonatina reasonably well. I only have enough time to practice for about an hour a day.
Examples of my 'dream' pieces are Chopin's 4th ballade, the Liszt B-minor sonata, and Rachmaninoff's 3rd piano concerto. Don't scoff at me - I have come to realize that it is simply not realistic for a 27-year old beginner to expect to ever play these, depressing as that sounds.
It is clear to me that there are limits of adult learning. (I don't think any person who started the piano at an age above 10 or 12 has ever played Rach3 in the 100+ years that it has been composed.)
Instead of harboring the above grandiose and foolish aspirations, what are reasonable 1-year, 2-year, 5-year, 10-year and 20-year goals I can set for myself? (I am looking for 1-2 pieces suggestive of the level of difficulty at each milestone.)
