Its colotomic structure is:
- pTpW pTpN pTpP pTpG
where p indicates the strike of the kempyang, T the ketuk, P the kempul, N the kenong, and G the simultaneous stroke of the gong and kenong. The W indicates the wela, the pause where the kempul is omitted. Thus, the gong plays once, the kenong divides that into two parts, the kempul (or wela) divides each of those in two, the ketuk divides each of those further in two, and finally the kempyang divides each of those in two. The kendhang usually plays in kendhang kalih style.
Ketawang usually have the specific form of an ompak that lasts one gongan and may be repeated several times, and a ngelik that may last three or four gongan. Some ketawang have the same ompak but different ngelik. Ketawang often begin in irama tanggung and then slow down to irama dadi or slower.
