Stones seem to enjoy any joyful sounds we make. Although I like to play directly onto stones with didgeridoo, while drumming I usually just place stones where they want to be. If I want to clear a particular stone, building, area, etc., I look at it while drumming with that intention. Our eyes can be quite powerful. Pay attention to how your body feels to check progress. Is there tension, antsy feeling, etc.? Take your time until you feel somewhat smooth and the same all over.
Regarding different frequencies, intention sets the stage, but different sounds effect stones differently. It is the same with humans. I have had people who love high frequencies avoid lower ranges like those of didgeridoos and drums. My knowing told me the low range sounds and the earth spirits they call can perform powerful healing, but as usual, the person in question must be ready and give permission.
For years I have worked on clearing and balancing the entire range of vibration that I am, rather than attempting to move into higher frequencies. The higher ranges are a great place to rest, but for me anyway, we need the lower ranges cleared as well. (For the cosmic party. Remember?)
