The staccato string sequence functions as:
Short, accented bow strokes (spiccato / marcato articulation)
Repetitive rhythmic ostinato figures
Usually in lower strings first (celli, violas), then reinforced by violins
Often harmonically static or pedal-based
Driven more by pulse than by melodic development
Kinetic writing, sounding like airplanes in dogfight, high risk speed, with reconnaisable sections, that appear melodic like trance refrains, percussion tempo alters, giving groove, or epic dimensions.
