What is the vanishing point in the painting

I think it's the last house where it seems to be both points pointing too.

Explanation:

The vanishing point in paintings forms part of a linear perspective scheme. It is the point in fictive space which is supposed to appear the furthest from the viewer - the position at which all receding parallel lines meet.

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 !
