I'm gonna give some real motivation.......
My name is Jonathan Diaz,I grew up in Puerto Rico, I'm 26 now, and started playing piano when I was 13, but I started playing classical when I was 17,,,. In that year when I was 17, I had a bet with a guy from my school, to see who was the better pianist,,,, I lost badly,,that moment triggered something special for the rest of my life!!!.... I felt so bad about myself,, that I said to myself I was gonna practice the piano till I was the best!!. Ironically, my father bought a grand piano for the house, that same year. It was in February 2003, The only pieces I could play at that moment,, where Fur elise, chopsticks lol,,the first movement of MOzart k535 and Chopin waltz # 64 right!, just common pieces you find on any casio keyboard!! lol. I started listening to the most famous classical pieces like, Moonlight SOnata, Fantasie Impromptu, Rhapsody in blue, Hungarian Rhapsody #2 , Clair de lune and so on. I don't remember witch one I started practicing but I assure you, I managed to figure out how to play Rhapsody in blue in the summer,, it took 2 months day and night till I got it, I'm not lying its the honest truth!..And it stills is the best one that I can play!. Now I had just a tiny amount of skill when I started playing again in february of that year, but I played and played, and when it was summer I poured my heart out to rhapsody in blue witch to me its the most beautifull and exciting piece for any pianist to play!. BUt before that In february, I started learning, more easier pieces like, Chopin Nocturne opus 9, clair de lune, fantasie impromptu, Wedding day at trouldhagen, moonlight sonata, and then Hungarian rhapsody #2 liszt,, yes I played that too!, and very good I might add!!, and I managed to aquire the tecnical skills necesary to play rhapsody in blue. The next year I was accepted to study in the Conservatory of Music in puerto rico,, after playing just a few pages of rhapsody in blue in the audition, Ironically, I never got to be a proffessional pianist, because I had problems in college, and opted for a career in music production!. It may seem hard to believe that you can learn all those pieces in less than one year, and play them good, and on top of it, not having the skills necesary to learn them, O and without a teacher, but believe me, I DID IT!. HOW DID I DID IT. Well first of all, I listened to the pieces each night for months, 2), I never stopped practicing, in fact the whole summer I literally did not come out of my house 3) I played till my arms hurted, 4) I practiced the hard parts like a million times, but the trick was, I put my laptop on top of my piano and I learned the pieces mostly by ear with a program called sibelius scorch (at that time), because I could not read music very well, but I did also learned them with the sheet music!,,but the real formula, is listen and practice, thats the key to do it fast, because if you just do it looking at the sheet, its gonna take some time,, and believe me, my interpretation of the pieces its right on point!. I dont know if I was born with the talent or what, I just now, I busted my ass off!
COnclusion: Of course you can learn rhapsody in blue, I DID, why cant you!!, anybody that puts their mind into something can achieve anything, but be carefull,, obsesion its not for the faint hearted!!,,, PEACE!!!............JONATHAN DIAZ
