This is a Wind Chime made of DNA Nucleotides Tuned Pipes. The DNA Nucleotides Tuned Pipes are a set of 4 Pipes , one for each mid-range tone (C#) for each nucleotide of the DNA. C# is the pivot pitch.The 4 Healing Tuned Pipes are based on Cytocine 537.8 Hz, Thymine 543.4 Hz, Adenine 545.6 Hz and Guanine 550 Hz..Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. This DNA nucleotide Chime is carefully constructed to activate body chemicals that are the very essence of life - Cytosine, Thymine, Adenine, and Guanine. It helps recreate an ancient form of gene therapy.These pipes are made from High Quality Heat Treated Aluminium Pipes producing beautiful and long lasting sound.Carefully tuned to actual frequency as mentioned.Gives Great healing effect.Dimensions of Pipe-Length - 20.5 inches appx,Diameter - 1 inch appx.
