Segment 2 presented a flow of an Abstract Expression to a Song about a Plum Tree. Segment 4 is a mirror image, offering a Song about the prolific, beautiful and exemplary Rosemary that graces the Rainbowland landscape, flowing into an Abstract Expression. Abstract-Song / Song-Abstract. Bridges of mirroring symmetry, framed in three movements of symmetry. The album structure is now revealed. Fun stuff.
