Thanks again to all of you, especially to you demonic_advent, for the shear volume of pieces that you have named.
I have listened to all of your suggestions and found them all really interesting. I must also say thanks to nathenscoleman for drawing our attention to the "Totentanz" I thought it was realy cool and just the sort of piece i'm looking for.
A small observation I would like to share with you all, on something I have discovered in my own Writing, some of you may disagree:
I've found Writing in minor keys, producing dark sinister music, a lot easier then producing happy uplifting music. For some reason, if you start with a mind to "go dark", but then mess up I would vew that section of the piece as simply being "more experimental" the fact that it might be more "A tonal" doesn't seem to be of to much consequence, other then giving the piece a more weird edge.
But when writing uplifting pieces, if mistakes are made the result is basically worse, and stands out as somehow being more out of contrast. Whilst trying to write happy melodies, I often think, "Ahaa, what I have just written here.... if indeed it has a name, is actually some cheese!"
It's taken some time to cull the happier elements out of my writing, but now I am finding writing a lot more fun.
Thanks, just my opinion, as I am by no means a skilled composer and struggle at writing, for me though, this small personal rule has seemed to of helped.
