If, like me, you’re an.. energetic.. drummer, then you may find the Rock Band drums mysteriously ending up further and further away from you after every song. This is not only annoying, it can actually screw up your drumming. As the distance between you and the drums grows, it interferes with your timing and muscle memory of where the drums “should be”.
As mentioned in Learning to be a Better Rock Band Drummer, it’s crucial to get the those drums locked down so they don’t move around on you as you’re playing. I should also warn you that if your drums are moving a lot then it’s highly likely you aren’t using the kick pedal correctly; definitely read the article on drumming to understand why!
One option is to use weights, if you have any. A few strategically placed weights can prevent the drums from moving as you play.
If you’re not on a carpeted surface, I recommend buying one of those friction anti-slip rug mats. I bought an 18 inch x 30 inch “rug grip for use on hard floors” from Target and it fit almost perfectly. I cut some of the excess off to use under the kick pedal and the legs.
Others have recommended taping the drums down (this might be frowned upon in some households) or using rubber anti-slip floor tiles — or even a small section of carpet, if you’re on tile. Whatever method you use, be sure to lock those drums down so they’re not moving around on you as you play!
