Get a wheelie bin, turn it upside down and bang it until they decide a drum kit would be more tuneful
Most parents aren't thrilled with the thought of their child playing the drum at first. They're thinking about the noise. So if you really want to play the drums, you have to get past this concern. If you have a basement, ask your parents if you could set the drums up there. If your room is big enough, that would be a good spot. If your weather doesn't get too cold and you have a garage, you could practice out there. In addition, parents are concerned that their children won't practice the instrument after they get it and it will be a waste of money. Tell your parents that you will absolutely practice the drums, then follow through with that promise!
Think of a few good reasons you should have one ex: It will help me practice ect.
Keep the drum set at a friend's house where they are not home often or they just don't care. (tell your friend to make sure that the younger siblings don't touch it).Once you get permission to do this, you can go over there all you want and get your full of practice. It doesn't even have to be a friend at all. It could be some grownup that you know. Just make sure that you have easy transportation to the place.
