What will be an ideal response?

• The nafir trumpets and the mazhars play a repeating ostinato pattern.
• The metrical rhythmic patterns alternate between six-beat units that are grouped into two groups of three (1 2 3 4 5 6 1 2 3 4 5 6) and three groups of two
(1 2 3 4 5 6 1 2 3 4 5 6)—see also explanation of sesquialtera metrical rhythm in Instructor's Manual Chapter 9, Question #9.
