Any man worth his salt will stick up for what he believes right, but it takes a slightly better man to acknowledge instantly and without reservation that he is in error.  Andrew Jackson 
Vibrational Modes of DrumsDrums resonate in various ways, creating different vibrational patterns. A mathematical language has been developed to define the different resonant vibrational mode patterns in a circular membrane. The scheme involves counting the number of directions (0 means it goes in all directions) and the number of nodal rings. (Number of Directions, Number of Rings) Here are the most common drum modes. Click on the picture to see an animation of each mode.
