Shapes.

Explanation:

Shapes has two-dimensions, height and width, and are usually defined by lines.

This ultimately implies that, height (length) and width (breadth) are the two dimensional quantities that makes up a shape. Also, the shape of any physical object is directly defined by either straight or curved lines depending on the type of object.

Some examples of shapes in science or art are rectangle, circle, polygon, square, cylinder, cone, sphere, etc.

Additionally, shapes in art can either be geometric or organic.

and the statements

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
