I Will never buy a piano as long as I live, electric keyboards are alot more versitile. I have a Triton Keyboard right now and it feels and sounds like a real piano, but I also like to compose some stuff and you can't save or have different sounds on a piano.
I am to the point where I think reading piano music is pointless. I can read and play the hardest peices of music on the violin but on the piano it's damn near impossible... I mean, i know what it is telling me to play but it's just not very practical.
like I said, learn your chords, all of them... There are over 1,000 different chords to learn and you will be sup rised how easy it is to pick up music when you know them.
For instance, just 2 days ago I was sitting around with 2 friends, killing time before I was going to the club, and the new Kayne West song "Diamonds are forever" came on. Now instinctivly without even paying attention, I was fingering the chords with my fingers like I was playing the piano. One of them asked me did I know to play the song (he is just as good as I am on the piano, but I am better at playing by ear). I never played it, but I know I can. By listening to it I knew the song was in B so I grabbed a keyboard from my room and by the end of the song I had it down perfectly. It's pretty easy.
I tend to play classical music on the violin, not the piano, my favorate song(s) are the Theme to Shindler's list which i can play on both the piano and the violin and Remembrances which happens to be on the same soundtrack. (if you haven't heard this sound track as of yet, buy it, even if you aren't in to classical music. I own over 500 CD's and this is heads and sholders my favorate one). I can play Remembrances on the violin, and it's actually not that hard to play on the piano but doesn't sound the same.
Believe it or not, I love to play music from Video Game soundtracks. They usually have some of the most diverse, prettiest songs on their soundtracks, espically the more popular games. I actually talked my orchestra teacher in high school to let us play play a peice from Onmishua once I found the sheet music. My Favorate video game song that I like to play is off of the Metal Gear Solid 2 Sound Track, it's a Jazz peice called "Can't Say Goodbye to Yesterday", it's the song you get once you beat the game.
Back to the point, learn your chords, it will save you alot of time in the long run. once you do this, alot of the stuff you do with your fingers believe it or not becomes instinctive. I hardly ever have to actually think when I am playing the piano, it's more of a enloagted motor reflex.
