To be honest, I don't think you are anywhere near ready to play this monstrous piece.The ballades are perhaps the epitome of Chopin's technical and musical mastery of the piano. They contain the elegance of the waltzes, the technical brilliance of the etudes, the capriciousness of the scherzos, the beautiful melodies seen in the nocturnes, the grandness of the polonaises all within the span of 10 minutes give or take a few. If your only experience with Chopin is the Funeral March and the 2nd nocturne, then you probably need at least 2-4 years WITH a teacher to be able to give this piece somewhat justice.As for the musical aspect, without a teacher I really do not see how you can play this. I suppose you could develop your technique but really without a teacher, all you are going to end up doing is butchering this piece. Chopin requires certain musical subtleties. Bringing out the melody is probably 5% of all the musical challenges presented by the ballades. You have your articulation, pedaling, voicing, balance, tone, color, dynamics, structure, etc. etc. etc. to take care of. Every note you must keep these things in mind. I would strongly advise against playing this piece until you have studiedat least 1-2 more nocturnes (to develop expressiveness and tone)3-4 etudes (you definitely need the technique)1-2 waltzes, these aren't exactly necessary, but if you can't play gracefully yet, start with thesemaybe 1 polonaise for extra technique and boldnessAnd if you don't want to butcher the piece, a teacher is absolutely necessary.
