Use four dice to roll a challenge pattern that combines the Ten Tsukutsu Ken (TTK) jiuchi with quarter, eighth, and sixteenth-note "fills".
The jiuchi pattern, TTK, is played once, interspersed with any of six other "fills", determined by rolling four dice.
The numbers on the dice correspond to the following fills.
1: ten su su su
2: ten su ten su
3: ten ken ten ken
4: teke teke teke teke
5: tsuku tsuku tsuku tsuku
6: silence
A roll of 2, 6, 1, 4, for example, creates the following challenge pattern.
TTK
2: ten su ten su
TTK
6: silence
TTK
1: ten su su su
TTK
4: teke teke teke teke
After rolling a combo, practice it at a slow tempo until it becomes fluid and the transitions smooth. Speed it up to your maximum, in-control speed. Practice there 8 times through the whole pattern. Then roll again and repeat.
