What did von Petzinger find in her studies on geometric signs? Briefly describe some key points.

Paleoanthropologist Genevieve von Petzinger studied rock art sites across Europe and discovered that Ice Age Europeans employed just 32 distinct geometric sign types from 40,000 to 10,000 years ago. The preliminary findings took her by surprise. ... It suggested instead that the signs' origins lay somewhere else.

Explanation: give me thanks and

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 !
