Hikaru Umi (光る海) practice

In koto, we are currently working on a piece called “Hikaru Umi (光る海)” for the Middle School Concert. I chose three sections where I felt I especially need practice, and they are:

1. Page 1 line 3 measure 3~ Page 2 line 2 measure 4

I need to work on the transitions when the strings are apart because sometimes I mess up and play the wrong string, and I also need to work on the presses because my presses tend to be too weak. I will practice them by repeating it many times and getting used to it.

2. Page 4 line 4 measure 3~ Page 5 line 1 measure 4

I need to work on the transition between the “五” “十” press because I am not ready for the presses sometimes, and I also mess up with the strings. Also when I let go of the press in a bad timing, it makes a strange sound. As I mentioned earlier, I will practice the presses many times and get used to it.

3. Page 7 line 4 measure 2~ End of page 7

I need to pay attention to the fingering, and also work on playing the strings smoothly. I will practice this section in a slow tempo at first, and then gradually increase the tempo.

Here is a recording of me playing one of the sections, page 1 line 3 measure 3~ page line 2 measure 4:

Brain Myths – Reflecting on the Impacts of Science

The human brain is very mysterious, and researches have discovered numerous myths about the brain. I chose to look at one of the myths, ‘People are either right-brained or left-brained’. It is true that there are 2 hemispheres in the brain, but this myth is not true.

However, there are many people who believe this myth. They say that throughout history, the intellectual skills of humans were often divided up into two classes: critical and analytic skills as opposed to creative and synthesising skills. Arthur Ladbroke Wigan, who is the author of the book “A New View of Insanity: Duality of the Mind” (1844) describes the two brain hemispheres as independent parts having an independent will and way of thinking.


According to the theory of left-brain or right-brain dominance, each side of the brain controls different types of thinking. Additionally, people are said to prefer one type of thinking than the other.

According to the right-brain dominance theory, people who are “right-brained” are often considered to be more intuitive, thoughtful and subjective. Also, it is said that they are good at expressive and creative tasks. Some of the abilities that relate with the right side of the brain are:

  • Recognizing faces
  • Expressing emotions
  • Music
  • Reading emotions
  • Color
  • Images
  • Intuition
  • Creativity

People who are “left-brained” are often considered to be more logical, analytical, and objective. Also, the left-side of the brain is considered to be adept at tasks that involve logic, language and analytical thinking. The left-brain is often described as being better at:

  • Language
  • Logic
  • Critical thinking
  • Numbers
  • Reasoning

This myth can help us in a few ways. This myth can help us understand our strengths and weaknesses which can help us learn more effectively by finding out better ways to learn and study. For example, people who have a difficult time following oral instructions might learn better when they write down directions and develop better organizational skills.
