How drums produce different frequencies:


Just like a flute, for example, drums have harmonic frequencies, i.e. a frequency in which the sound is ‘stable’ and consistent. and just like a flute, there are multiple harmonics, the first being one in which the entire membrane moves as one, up and down, which is shown in the first gif.

The next harmonic causes the membrane to split into two sides, one going up and one going down, which occurs at a frequency 1.59 times larger than the first harmonic frequency. the first frequency depends on other things such as size and material, but from then on all frequencies are specific multiples of the first.

The second gif shows, i believe, the 9th harmonic, and the third gif shows the 8th.
