Learning to play keyboard

realy, start by seriously learning an instrument.

lol this is one stubborn child. fine, if you don't think you'll be playing the keyboard much, then don't even bother with it, just write your little theme songs on the computer. hopefully you'll start to appreciate the importance of keyboard playing one time or another, and only then can you start learning with real dedication.

I don''t think it's one hundred procent absolutely necesary to play an instrument, but it will help you so much. Making music is a very diffucult thing to do. If you want to make music that has some meaning you have to learn a whole lot. Things seem always easier when looked upon than when you are actualy doing so. (skien is just putting you skies down and don't look back..sure). If you don;t have an instrument whereto you can relate all the theorie you'll have to learn it's even harder to learn how to make music. Do as you please and i'm saying it without any hard feelings. But believe me when i say that making music is very difficult, perhaps much more diffucult then you think beforehand and if you realy want to do so playing an instrument is very helpfull.

Keyboard is definitely an awesome way to go. I salute you for that! I might invest some money in a music theory book (any will do really) and figure out some chord structure. From there just play around on said keyboard. Hear the chord, get it in your head. That's a fantastic way to start training your inner ear to hear anything you want to compose. The biggest deal is learning all the notes then fooling around, you'll eventually teach yourself some basic piano. Your technique might not be perfect, but unless you intend to get serious with piano, that all you'll need.
Hope I've helped...

incidental music Is what i`ll be doing no idea what i need to do and such yet tho as far as i know virutual instruments are important aslong as im not mistaken

incidental music or not, if you enjoy writing music then i dont see why you wouldnt want to play an instrument. you dont have one yet, so how would you know? get a cheap keyboard, and if youre serious about playing, get a teacher. composition will come on its own
