Concept:
Using the standard rhythmic position formula, we compute how much time an accelerated composition track takes up within the boundaries of a single rotation (Aavartan).
Step 1: Calculate the space occupied by the Tigun segment.
• Rupak Taal consists of a total length of 7 matras.
• Tigun (triple speed) means playing at a density of 3 notes per beat.
• Performing one full loop of Rupak (7 structural notes) at triple speed consumes a duration of:
\[
\text{Duration} = \frac{\text{Total Notes}}{\text{Speed Density}} = \frac{7}{3} = 2\frac{1}{3} \text{ matras}
\]
Step 2: Deduct from the total cycle capacity to locate the starting point.
To ensure the phrase finishes exactly on the next Sam, subtract this duration from the total 7 beats of the cycle:
\[
\text{Starting Beat Marker} = 7 - \frac{7}{3} = \frac{21 - 7}{3} = \frac{14}{3} = 4\frac{2}{3} \text{ matras}
\]
Thus, the performance must start immediately after \(4\frac{2}{3}\) matras.
