I remember when I've heard Aïsha Devi for the first time and decided to find out some more information about her, she said in one of the interviews that she studied sounds engineering and sounds influence on body. It isn't a black magic but widely explored academical fact. Good that you touched this topic on steemit. Below we can listen to her attempt to sonical brain massage :)

BTW, I dont know if you heard some news related with steemit but thanks to implementation made on beta.steemit.com, now we can use #hive-193816 to engage music community even stronger. It is already a community made from 81 subscribers and 24 active posters supporting each other. Your musical knowledge can bring lots of good for the people and blockchain. Using steemit.com, you can just use it as one of the tags under your post, recommended as the first one, in other apps it works probably similar.

Peace !
