Before you reply, I can think of a reason why it isn't correct.
| The kettledrum produces different tones depending on whether it is struck with sticks or not. |

We need an object after 'depending on.' And 'whether' functions as a conjuncion which needs a noun phrase to form the object complement of 'depending on.' Then, that it is struck with sticks is a noun phrase.
I hope you know what I'm saying.
