Hallo buddy!
Okay, so putting aside any comments about notation or score format which I don't have on account of not giving an immediate shit about them, I will focus my response on the music, considering that's what I assume you care about.
I will also refrain from commenting at any length about your violinist. He plays.
Moving right along, the piece itself spoke to me and I really liked that. It had a certain stately elegance to it and it was undoubtedly tinged with your incidental side, but what I liked about it was how it melded that into a concert piece that's very accessible to a not high-brow audience. That is REALLY important these days, I think, for those of us just trying to "break in" as it were.
Besides having memorable thematic material, I thought that your harmonic development (much to Danny's chagrin) was a point of interest for the piece - it helped really define the progression for those that aren't aware of any particular reason why it might be defined as "inconsistent".
I liked the interplay between the instruments too, and I'm happy that you gave the piano such a pretty part. That bit where it plays alone really solidifies a certain "mystical fantasy" sound that the piece stereotypically adopts. I was happy with that.
Overall I really enjoyed this piece, especially because of that fact that it is, as I mentioned, such an accessible concert work. It doesn't require someone to be a stuck-up music nerd to be able to appreciate or understand it - it might even be bad to those people. But for an everyday audience, they can just go in, listen, and enjoy it for its pleasing sound. Big kudos from me for that.
Congratulations on getting it performed and thanks for sharing!
