There are a couple of notes that the french horn hits that I'm not sure is actually in the real range of a typical french horn player. Those really really high notes are coming to mind. I play french horn, and it seems like some of those notes are just awfully high for the instrument. I could be wrong of course though.
As a composition, I like it. But I don't love it. It is too repetitive, especially considering how short it is. It really runs the same idea and chord structure over and over for the brief 1:13 of it's existence.
Now that being said, this is a beautiful piece. It sounds quite wonderful, and has a great atmosphere to it. I feel like I should be climbing a mountain, or preparing for a battle when I listen to this. It really has that epic and majestic quality that leads a character to some sort of epic undertaking or conquest.
The percussion is really nicely done to say the least. Very nice indeed, and it simply adds to the atmosphere of this piece.
4/5 and 8/10 overall. Wonderful job here, just not quite great yet.
