Haha well it's definitely more a skill than a science. I wish I was better at putting that skill together. It's funny that I can improvise really complex bebop solos, with lots of theory behind them, on the spot, but when I open up audiotool everything I know manages to escape me XD
(link is only visible to registered users) You're absolutely right about that, I originally had an intro for the track actually, but I scrapped it because it was even more out of character than the buildups.
The melody is slick 50. I'm not a fan of the buildups. They are really out of character in comparison with the rest of the song. Also, the best video game tunes don't just straight up repeat the tune; they have an intro that is only played the first time through, and THEN they go to the looped part. Just some things to consider. I like the percussion.
