Thanks to this fandom I have become interested in making music. I'm pretty much a complete beginner and I don't really know where to start. So far I have been learning/reviewing music theory, researching online, watching tutorials, and of course reading through some of the threads here in this forum.
I used to play the violin before (not too bad I guess) so I know how to read music and such. But, while I'm studying about theory such as scales, chords, and intervals, I have a hard time understanding how to put the theory into practice and make even the simplest music while experimenting. It's kind of giving me a headache. I'm wondering how to create a melody, how to build a basic structure to help me build a complex song, how to get ideas, how to create a beat, which keys/scales I should use, which instruments or synths I should use etc... (lol I am all over the place, aren't I?

I don't know which genre I want to learn but if I have to choose it's probably going to be something electronic, whatever OdysseyEurobeat/Ponybeat, iamnotacleverpony and other popular brony composers make...
I currently have Garageband on my computer and FL Studio 10 (demo) on another and probably will be using mostly Garageband and switch to FL Studio once I get a new computer. I'm not willing to spend any money just yet in case I find out that composing music isn't my thing (although I understand that giving up halfway isn't good). I'm going to just treat this as a hobby since I probably can't become a professional.
Could anypony help give me a direction where to go?
Thanks!
