Manga name???

I remember it was a manga and is completed. The plot and storyline was all over the place, but the art was really nice. The main parts I remember is that there were instruments that looked human-like (Androids maybe). One of the main characters was a female violin (or was it organ?) that can't be played by majority of the people I think. She was a unique instrument type and was one of a kind made from a dude who was somewhat important in the storyline. And there was another guy whose background story got so confusing at the end but was like a temporary companion with the girl. One fragment of the storyline was that a being stole all songs and music and claimed that it is all his so creativity for music was dead. Sorry for my rambling, my memories are a mess. (￣∇￣")
