5 prong wind chimes are excellent in dispelling negative energy. I find 5 prong wind chimes are also excellent in creating a change of energy in your life or home. You can place your wind chime out side or inside. Wind chimes are great to place in your career path and at the front of the home. If you feel you have any negative energy around your home they are excellent in dispelling the negative energy. Great to hang from beams on verandah.
