The equilibrated music !

[Toccata]

In the nature, like in the life and everything being, there are the basic equilibrium named by Zen, the yin and yang, two opposited forces that complement and depending between themselves to give the harmony!
Male and female, day and night, cold and heat, bitter and sweet,etc.......
The same principle are in the music too, ever following to an equilibrate situation!
Even more in the Prog. Rock which through Synths , effects, etc. Many sounds are possible to obtain since the most agressives until the most delicates !!
This thread we can put names of works and groups which this principles are well used!
Of course , there are an infinite of songs!
I begin my vote with The lark's tongue in aspic of K.C!!
Who can vote others!!
