The Harmonic Chapel was completed in 2012. At baseline it is a sound/chant resonator. It encompasses a central vault and six alcoves of variable sizes. Sound focalizes along points and lines where people are. Through voice, toning, and chanting it is possible to interact with this and create internally sensed interference beats in any part of the body. Overtones and undertones play this. It serves as a sauna as well 2-3 times /week. Here are pictures of the completed structure. See link below to old TerraSante site for historic details.
