852 Hz 即是 LA，在 Solfeggio 傳統中被視為回歸內在秩序、喚醒直覺的音頻。 它落在眉心輪（第三眼），洞見的所在。這份意涵源自傳統，獻予你細細沉思。 Solfeggio 這些名稱，源自中世紀一首獻給 St. John 的聖歌，Guido d'Arezzo 曾用它來教導歌者：Ut、Re、Mi、Fa、Sol、La。到了 1970 年代，Dr. Joseph Puleo 表示，他從對 Book of Numbers 的數字解讀中，重新尋回了一組六個音高，而 Leonard Horowitz 則將這個想法帶向了更廣大的聽眾。至於把這六個音對應到七脈輪的階梯，則是後來添上的一層虔敬詮釋，是一種將音階聽作在身體之中拾級而上的方式，而非源自原始傳統的主張。 Independent of any tradition, controlled clinical evidence that a specific frequency produces a specific health effect is limited and mixed. Auriviel presents these tunings as music and contemplative practice. This page is for general information and relaxation. Auriviel's frequency music is not medical advice, diagnosis, or treatment, and no health outcome is claimed. If you have a medical concern, please consult a qualified professional.
