Simple Deep Muse of a tale of an emotional search
This is one of those soundtracks that doesn't need a game or movie to give it meaning. In fact quite the opposite, "Searching..." gives itself it's own worth through it's continual yet gentle and deep melody. Should add great emotional backdrop on the character's journey. I'm still curious about the storyline of the game this is going to be made for...but that's a small detail in comparison to the ideas and story "Searching..." hints at.
As for the structure of your song, the song does not bore one bit, the melody and instruments changes and repeat apporiately. A theme melody can be found within this simple song.
The song did noticeably restart at times, (half second of silence and then an abrupt pitch shift), but that seems to be more so due to the NG player lagging than compositional or recording fault, but noting it anyway due to it being the only noticeable interruption to the mood of the song.
As for the introduction and fading of the instruments, the hard piano and strings come in gradually and to a powerful effect, giving the song a more profound swirl of energy that helps perk up the listener's attention (as opposed to the emotional backdrop that the drone was providing). As for the exit of the hard instruments and piano, the repeat wraps off it's part melody quite nicely by signifying it's own end and yet letting the drone carry on without leaving an awkward feeling.
The droning (soft) piano helps carry the overall melody when it comes on it's own and complements the hard melody when it comes in to bring more life to the loop. Though I couldn't help but wonder how a song/loop would do with just the simple drone by itself, for it seems to hold it's own so well.
This is a beautiful rolling hill layering you have here.
As for the instruments, I wonder if you used live instruments due to the clear sampling.
Regardless, this is a beautiful piece you've composed, I've been listening to this non-stop for well over 20 minutes as I write this review. Can't wait for the release of this game and more importantly, more compositions from such a talented artist such as yourself.
