I recommend a couple tools for making music
I recommend two tools to beginners at making music- Fruity Loops Studio and Anvil Studio. Fruity Loops Studio is much, much more complex, but sounds very, very nice, where Anvil Studio is a MIDI music creator, which requires more work to sound real, but is much, much easier to use.
Anvil Studio is what I use if I want a solid score, I use Fruity Loops Studio to play around with music, partly because of its realistic instrument synthesis. All in all, I don't buy either, simply use the trial version (and Audacity if I wanna export from FL), and enjoy what I can do with my limited musical knowledge.
