The colotomic structure is:
- ...N...N ...N...N

Gongans are of varying length, according to the pathet. The ending (suwuk) can occur at any point in the cycle, given the cue from the kendhang or kepyak. The melodic shape of a srepeg is distinctive, as it consists mostly of the seleh alternating with a neighbor tone.
It is usually fast and played in irama lancar.
