Dear friend @artemislives
I knew that you would be happy to see this work, we always do it before singing, I remember that our master confessed to us that he does it since he was very young, he learned this technique of relaxation, breathing, concentration, and focusing from a master who studied outside our country.
Here in Venezuela, many people still don't believe in this method, they believe that it is part of a ritual of sorcery, or something like that.
Currently only some masters teach this breathing technique before singing, but it is also good for dance, theater and so many other things, as you say, for everything is good....
**I particularly think that if it's part of a ritual, it's a very beautiful ritual that makes us sing like angels, and if it works, it's perfect.
