What about getting some graded repertoire with CDs?Like the Hal Leonard "getting to" series, or the Kjos Keith Snell series?That way you could teach yourself grown up pieces by copying the recordings??And whenever you meet someone who plays better than you ask them to listen to you and give you some pointers.
dear roseli,of course, the basic idea is to find a teacher, but in the meantime, a couple of advices that could be helpful.first and foremost, don't do any hanon! it's a complete waste of time and a constant risk to your hand and arm. then, focus on the music you like and forget about side repertory that you don't know even the name of the composer, simplifications, and step-compositions such as czerny studies.that said, what to play? schumann's album for the young op. 68 (the one where your piece by him come from) have another delightful works. in the same fashion, tchaikovsky's album also have interesting (though a bit harder) pieces. if you like the russians, look also for shostakovich, stravinsky, kabalevsky: they all have very simple masterpieces.then, there are composers and works that you must play (basically, yes or yes): on the top of the list, bartok's mikrokosmos, followed by bach's anna magdalena notebook, and easy pieces by haydn-mozart-beethoven. well, that's a lot of stuff to look at, and most of it are in the imslp.org portal.best regards, and enjoy!
I don't like that kind of method of learning, I want to learn to read music not copy from recordings.I don't know anyone else that plays.
