Final answer:
The instrument not used in the Ibalon Festival street dancing is Chimes. This traditional event in the Bicol region of the Philippines typically does not feature chimes in its musical lineup. The correct answer is option D.
Step-by-step explanation:
The instrument that is NOT used in the Ibalon Festival street dancing event among the options provided is Chimes (Option D). The Ibalon Festival, celebrated in the Bicol region of the Philippines, showcases street dancing performances that typically feature indigenous music and instruments. While instruments like rainsticks, the kubing (a Philippine jaw harp), and cymbals could feasibly be part of this traditional event, chimes are not usually associated with the festival's musical ensemble.
Therefore, the chimes would be the correct answer, as they are not part of the traditional instrument lineup for the Ibalon Festival's street dancing.
