I think I would be talking about harmony/structure purposes for healing, and joyous experience. Classical music in general gives me the most joyous experience, out of all music styles. This is where it's form comes into play. I don't think I have the musical knowledge to define exactly how it works. It's the energetic reverberation of the strings in perfect resonating harmonies. Strings are definetly key to the music that I enjoy from this style, also choral is wonderful two. I think that some baroque would also qualify especially bach and his brandenburgs which are excellent. I definently think it's dependent on the listener, but classical music seems so harmoniously resonate, it's definetly has a very large audience.

Mostly what I'm talking about is joyous experience while listening to the music.
