The modes of a circular drum head are described by Bessel functions and sines and cosines, but without getting into all that, one can making the following statement: the nodes are circles concentric with the center of the drum, and are also evenly spaced lines that run through the center of the drum (i.e., diameters).
However, while watching this video on youtube:
the first few modes are all right, but later on at higher frequencies, the modes don't seem to meet the description above. Why is that?
