Stress often comes to everyone suddenly, without prediction, and sometimes makes us ruin our relations with our beloved one or other people around us. A lot of work, disturbance while doing something, and a lot of things around the world that makes us blow out of our mind. The bad thing is it is hard to avoid. It is happening to adult and even children. What may cause it, is our hormone inside our body, called cortisol or stress hormone.
Cortisol is produced while our body or our psychological is in stress. Nonetheless, cortisol not always a bad hormone, we also need it. In a proper dose, it can help us to be more alert and concentrated. But in an excessive amount, it will cause a lot of diseases, including heart disease, hypertension, and many other diseases related to it.
The researcher has made 22 kinds of research and the result is remaining the same, that listening to a music with some settings can reduce cortisol levels, even when it is located in a hospital or laboratory. Right now, they are trying a new research related to music. The research held in London, with 117 people as a volunteer. Next, the researcher has them listen to live music held by composer Eric Whitacre. They are collecting the volunteer's saliva to be tested in order to measure the amount of cortisol hormone on it. They took two sample; The first sample taken before the concert. And the second are taken during the concert. And the result is clear, there's a decreasing level of cortisol hormone in the second sample saliva which is taken during the concert.
The researcher is willing to do the other test with a lot of different things to try. They used to do this research with a classical music, but now they try a live music. Can't wait to know what the results are when they try with a metal. Why not? Since every research with a different genre of music has shown positive results so far. They also looking for an answer about the engagement between music, art, and cultural setting to human biologically, and even psychologically, for a very generous purpose, which is to enhance human health and become a well-being.
Usually, people listen to music by hearing it. But, for some artists, they could even ‘see' the music as a colour. This condition what is called with synesthesia. This known as a phenomenon of a neurological. Synesthesia is a condition when one of the usual sensories do the work, but then elicit with another sensory. By the former sample on this paragraph, the hearing sensory are elicited with the vision sensory.
The artist who have this ability and have revealed it is Billy Joel, Stevie Wonder, Frank Ocean, and Duke Ellington. Duke Ellington, the legend of jazz has said that he heard the note played with one of his band members, and it is in one colour. Then he heard someone else playing the same note, but it is revealed as a different colour. The people with synesthesia can see music manifested in many colours. It is so interested from where the usual people see this different.
Later, Melissa McCracken has interpreted this colour of music into a painting. The results are very interesting; Karma Police painted in many colours, and Prince interpreted in an aggressive stroke of the brush till out of the canvas. There's also another painting by her which is an interpretation of the synesthetic vision. There's also an Israeli artist called Michal Levy's who has to interpret "Giant Steps" by John Coltrane.
