Intriguing
Really good so far. I found myself playing along on my keyboard, it has great potential for additional voices. Even by itself, I think it can stand alone. The different sections can really back up a verbal story or message. What you've written so far calls certain emotions and depending on what you say vocally will define them. It's very versatile, I can already feel anger, hope, empowerment, even tragic just from the instruments, the overall tone will eventually be defined by the lyric. I just hope you can write an equally intriguing story for lyrics to complement the music.
I know it's not final but it needs an intro, those two bars of eighth notes aren't cut'n it for me. The transitions are okay so far. I'm assuming there will be some expansion on some of the sections. I'm also interested to hear how your going to close this.
As good as it's sounds now, it's still far from finished, I think this is something you'll have to dedicate some serious time to. All you can do is work on it until you've reached satisfaction with the piece. If your going to share the development of this with us on this web site, then please let me know when you post another submission. I would really love to hear how this evolves into a finished composition. I wish you good luck and thanks for sharing.
