I am an undergraduate student wanting to learn either Rach 2 or Rach 3. I figure a concerto takes so much time to learn, so I must pick wisely. And if I had to learn one in my life, it would have to be one of these two. I am pretty technically proficient: rep including Beethoven Waldstein, Chopin Ballades 134, Miroirs 2-4, Rach op 39 no 5, however, I'm aware that these concerti, especially the Rach 3, are a step up. I go back and forth between which I like more, and I like both for different reasons: Rach 2 sentimental, etc- Rach 3 exciting, etc. At the end of the day, which should I learn? Which would I get more out of? Which is worth grinding for? For context: I am NOT a full-time music student, I am a premed student amongst other things, and don't have time to practice hours a day. I also want to be able to learn lots of other repertoire while I'm still a student. As far as time constraints go, I would like to have the piece learned in two years, but I have no end goal with it and will probably never play it with an orchestra. Thanks so much.
