- ZynAddSubFX's concept of harmonics (strongly recommended!):

"Is it a common technique to use the bass drop of your kick drum (pitched up) for your snare drum?":
In order to answer your question, we can have a look at what happens (simplified) when a stick hits a real drum head. As soon as the stick touches the membrane it starts to transfer his kinetic energy to the membrane. The membrane will be tensioned until it has absorbed all kinetic energy from the stick (stick "stands still"). Then the process inverses. By relieving its tension the membrane transfers a part of its energy back to the stick (pushes it back). This change in tension of the membrane is what causes the short rise and drop of frequency during the first few milliseconds of sound.
How much time this process takes and how much the frequency changes depends primarily on two factors: momentum of the stick (mass x velocity) and consistency of the membrane. That means that a heavy stick played hard will cause a higher frequency peak, whereas a light stick played gently will cause only small frequency changes.
Back to your question: Yes, the membranes of a kick drum and a snare drum produce their sound based on the same physical effect. But their membranes are different as well as the sticks hitting them. So if you want to transfer the frequency envelope of a kick drum to a snare drum you will probably have to adapt the frequency peak and the duration of the frequency envelope.
By the way, the vibration of the drum head is only one part of the drum sound. The drum body also plays an important role because its geometry causes acoustic resonances. And for a snare drum, there are the rattling snares as a further characteristical sound component.
