Thank you even83 for your feedback, much appreciated.
I shot a sequence of images at 30 FPS.
Then made an endless loop gif animation at half resolution.
A full cycle required only 5 images, spaced 0.04 seconds apart.
The wind was blowing just right to excite the eigenfrequency of the upper yellow band.
That caught my attention. So I shot a sequence of images of the upper band oscillations.
