I'm not a musician myself, so I can't give any advice or even actively know what the heck I'm talking about.
Still, that was beautiful. I think it was your profile icon that made me click this (I may have commented on one of your other tracks before, now that I think about it. I'm forgetful I guess. :P) so I'll probably have this going while I play Dwarf Fortress. I think it will fit pretty well. Thanks for making this! :)
I like the title. Are you thinking of the Greek Pleiades or the star cluster? Even though this is ambient music, I think you may be writing too much emphasis on one chord (C# minor). It would be nicer, I think, if the harmonies moved around a little more, particularly in the middle of this track. That said, I'm putting this on my favorites list--that little melodic figure at the beginning and end is so beautiful, and so sad...
Please contact me if you would like to use this in a project. We can discuss the details.
