"Jha" is just like "Dha"
except the "Ta"
comes late. We call it a "Lazy Ta." With this stroke,
the two ends of the drum are not
hit at exactly the same time. One side (the small end of the drum)
gets hit a microsecond or two late.
"Lazy Ta" = "Jha."
It is often used with body language to highlight the lateness
of the "Ta" as in the animation on the right.
