Injucting Music to the Game

Ok here are some music ideas i have of how the game should sound. It was harder than i thought to find this but here is the best i could come up with:

This is how the atmosphere should sound like, try to imagine with some machinery sounds in the background like cogs and stream pumps...

This for the Victorian Intro or early stages of the level. Try to imagine the song with abit of machinery streampunky background to it.

This is a eerie piano song i thought could fit somewhere in the intro, or early stages of the game.

This is "Silent Hill Theme, called Butterlies" somewhere along the lines of the machinery sounds , try to imagine it alot slower and with less of a tempo, or it could work for the faster levels of the rotating rooms.

This one is another mechanic toon from silent hill i thought we could work with, I guess this one without the music could be something cool to add.

This is another piano song i thought we could use for ideas of how the game should sound

This is another piano song we could adapt to our victorian feel.

Somewhere along the lines, i thought would be a good idea would be to add a victorian music box circa 1870.

This i just thought was kinda cool how they did music using parts of instruments put together,{also a pretty good tune somewhere in there}

I think i getting carried away with eerie piano songs, heres hopefully my last piano entry.

and finally for now here a song i found fits pretty well as an overlay theme somewhere, with a few tweaks here and there:
