Thanks for the response.
I wouldn't call this a "showcase" of the most impressive melodies that I can come up with. If you'd like that, you can check out the other audio submissions that I've uploaded.
A "theme", to me at least, is usually a lot more repetitive and doesn't have a lot of crazy things going on because it doesn't want to take from the focus of what it's accenting as a theme. This is just my method. Could you not say the same thing with instruments and that it's the song we've written, but just behind the instrument? Just something to think about.
I also always have my keyboard and guitar, along with bass and other things near my computer when I work. I've been playing for over 12 years now so the learning process has slowed down, but I'm always open to trying new things to teach myself.
Thanks so much for the review <3
