A.6.3.RT.OE:5.3 - Coordinate a phrase with a recurring hand cycle
Use a learned solkattu convention in which syllables express a rhythmic phrase and hand gestures mark its cycle positions. The cycle has three beats, each containing four pulses, marked by clap, little finger and ring finger. The pulse remains constant.
The content to express is four successive ta ki ṭa groups with four, three, two and one pulses per syllable. Their durations are:
| Group | Pulses per syllable | Group duration |
|---|---|---|
| First | 4 | 12 pulses |
| Second | 3 | 9 pulses |
| Third | 2 | 6 pulses |
| Fourth | 1 | 3 pulses |
The phrase occupies 30 pulses. The twelve-pulse cycle supplies the recurring reference. To finish at a cycle boundary, rhythmic composition selects a six-pulse preparation: 6 + 30 = 36, or three cycles. The preparation can be voiced as ta ki ṭa with two pulses per syllable.
Prepare the vocal sequence against the continuing hand cycle. The phrase starts six pulses after the cycle origin and ends at the third boundary. Preserve the pulse and duration assignments through the changes of syllable rate. Merely placing four identical syllable groups on a page would leave those assignments unavailable.
The resulting expression coordinates two learned channels: phrase syllables and hand-cycle reference. Arithmetic and rhythmic composition determine the entry and ending. A performer can use that expression to produce the phrase; the utterance and gestures can both represent the content and realize rhythm.
For a performer who needs to locate the cycle boundaries inside this phrase, add these cues to the same pulse reference:
| Cycle boundary | Place in the phrase |
|---|---|
| Pulse 12 | Hold ki in the first group; that syllable begins at pulse 10 and lasts four pulses. |
| Pulse 24 | Begin ṭa in the second group; its syllables begin at pulses 18, 21 and 24. |
| Pulse 36 | The final ṭa has ended; the next cycle begins. |
The duration labels retain the whole phrase. These additional cues expose the positions needed for its coordination; use the compact labels alone when that relationship is already available to the performer.
This case adapts Nelson’s exercise 7. Reuse the pulse alignment when phrase and cycle change tempo together. Recompute it when a syllable duration in pulses, the cycle’s pulse division or the phrase’s entry relative to the cycle changes. A particular performer’s fluency remains a question for actual performance.
