If this make any sense, I visualize harmony as three-dimensional curves, you can imagine a set of three, four or sixteen planes one on top of the other, separated in heigth by some distance, but taking infinite different forms, touching and trespassing each other as the music goes. I see authors constructing entire buildings, cathedrals and heavens with these ethereal elements.

Not finding an end to the amazing harmonies of Bach, I got surprised by the marvelous Brahms, and then by the strange and beatiful Kodaly, and then by the new world of Ligeti, and by the depth of African harmonies. It is endless.

By myself, I can try some duettos, á la Sinatra/Minelli, but only as an amusement. Best regards, Andrés Magré (Escamillo á la Bizet)
