This is a kind of "Miniature Symphony" [very miniature at that - it only lasts about just under 3 minutes!], I've just recently finished using the new Sib4/GPO program.
Here is the link to my SibeliusMusic site web page mp3 file.
Hope you enjoy listening to it.
I created the audio file in Sibelius4/GPO by exporting the orchestra in sections as an audio file, then I added the Cakewalk Sonitus Reverb to it in my Home Studio 2004. So, what you are hearing is the audio file from Sib4/GPO with reverb added to it.
Obviously classical/modern influenced in the the harmonies are very tonal, but the meter is in 5/4 which gives it a bit of that modern feel I suppose.
