The intro is good - fat open 5ths are hot. The piano line keeps the energy moving, which is cool. The hard tonguing of the third entrance (what the hell instruments are those anyways?) ...the hard tonguing would be a bitch to play, and sounds a bit odd to me. I dunno.

The voicings are good - nice, clean. After the piano drops out though, there seems to be a hole, texturally in the middle - perhaps some sparse drums would help thicken it up.

I dig the fat chord right before the little...guitar? solo. The piece as a whole needs to be built up more, you've got a good foundation here, develop this material more - add more texture, layers and build the energy up up up.

This is weird...depending on instrumentation, it could be a metal tune, or a dark jazz piece. I'd love to hear it done with a jazz orchestra, with a shit-hot drummer freaking out...could be tight.

What did you intend with this? Is it a rock tune? Where are you going with it?

it's meant to be a little rock tune. i made this in guitar pro so sorry if the instrumentation is a bit wierd to figure out, right now i have piano, guitar and bass. I'm a complete noob to adding drums to tracks so i have no idea how it will turn out, thanks for the input though
