I've read that music is number in time, and art is number in space. Both give off a particular vibratory rate; but music is moving, and art is frozen. So in a way, each piece of art is like frozen music. 

My illustrations are frozen songs.

Some like a song for how it sounds. Some like it for how it makes them feel. Some like art for its content. Some like it for the feeling it gives them.

I was going for a feeling; something calm; the small rest between inhaling and exhaling.
