The long term one hundred

[chopin2015]

As great as playing through the piece by sight is for you, I also recommend conscious practice, such as targeting just a couple bars at a time in addition to playing through the piece by sight. If you are reading to familiarize yourself with the piece, you may find yourself spending a large amount of your practice time on just a particular piece. If you do a couple bars at a time, you will only have to go back to those bars probably just once your next practice. I only give this advice because you want to practice many at once? You have to be a very good multitasker to be proficient with your time and see results on every piece when you expect it. P.S some pieces you will probably surprise yourself and finish faster, others look difficult and turn out to be more difficult. Good luck!
