Oh, yes, and many of the Nazis were playing guitars, violins, and pianos, but they did not hesitate to spread all the murders and disasters first in Europe, and then in the whole world. And many of the Japanese played instruments and did not hesitate to bombard the Pearl Harbor. And many of the Americans played instruments and they threw atomic bombs to them. Sorry, I do not accept this article for any evidence that the music makes us for finding inner peace, harmony and the like. ELIMINATION OF FEARS does not come from such things. EXPERIENCES in life and prudence do not come from the playing of the guitars. The pleasures of the moment comes from Aristippus the Cyrene. Epicurus in his bed death did not ask for music, he asked for a glass of wine as an analgesic, and as he remembered all the past conversations on philosophy with his friends, and as he cared for the future generations with the children of Metrodorus. There are many musicians in this world that are idealists and living a life in confusion and fears about death and god.
The article that is posted as above is only speculations/opinions. For me it goes to the pseudoscience. It has the bad smell of <<idealism>> and the fantastic, and it has nothing to do with science and epicurean philosophy.
