Understanding usul
One cycle of Düyek spans 8 time units. Count 16 units across two complete cycles and mark the return at the second cycle.
The diagram shows the time count of one usul cycle. Consult a notated or performed example for strokes, stresses and mertebe. Several usuller can share a time count.

Can a time signature identify the usul conclusively?
Answer
Compare the stroke pattern and relative stresses too. The equal time units in the diagram do not specify a düm-tek pattern.Related topics
