Before putting your harp up think about where you will be to enjoy the sound. It is best if you can put it close enough to hear the sound, usually within 25-50 feet. Our harps work best if you put them in open, breezy area. Up in the air 2-5 ft also helps as breeze is more consistent. Please attach them to wood if possible, not to stone or concrete as that tends to deaden the sound. If you are using stone to mount to, put a wood board(1/2"-1") thick between to harp and the attach it. If you have any questions or concerns, please call or email me and I'll be glad to help. If you an send several digital pix of installation which can help, Dan
