What does the natural frequency of an object depend on?

Whenever I try to look this up, I usually read that the natural frequency depends on "intrinsic" properties or a "variety" of factors. Is the natural frequency independent for each object/is there any universal factor the natural frequency depends on?

No, it's always going to be a complicated function of what the object's made of, its shape, whether it has defects, the temperature, the humidity, etc. Generally it's not feasible to calculate the natural frequency of a real life object it's pretty much always much much easier to just find it experimentally.

Okay thanks for that.

Somewhat unrelated, if you were to, let's say, take a guitar into space. The guitar strings each have their own natural frequency. However if you were to pluck one of the strings, would a frequency (and corresponding wave) be produced? Doesn't sound, which is produced from such an event, require a medium?

--- Nevermind

The object would just vibrate, no wave produced.

Yes. The medium is: first the string, then the guitar body. The wave would not, however, propagate beyond the physical confines of the guitar itself without the presence of a medium such as air (or any other mass in contact with the guitar).
