The (1,2) mode
The fifth mode (1,2) has one nodal diameter and two nodal circles. The frequency of the (1,2) mode is 2.917 times the frequency of the (0,1) mode. As you might expect after looking at the first several modes of the circular membrane, the (1,2) mode does not radiate sound very effectively. It has somewhat of a quadrupole type behavior. Thus, the (1,2) mode takes a relatively long time to decay. However, this mode doesn’t seem to play a dominant role in the musical tone quality of a drum.
