Now is the time to tell you,I had the same problem as you, and I played the piano.

Even if you practice every day, the sound will never improve. I can't play fast passages.

I also had many piano teachers.

As a result of continuing to practice unreasonably, my hands hurt and I couldn't play, and on top of that, my bones were distorted.

I was depressed to the point that it would be difficult for me to continue playing the piano.


Still, there must be a secret way of playing the piano that produces the most beautiful sound in the world!

I wanted to know it no matter what, I wanted to wear it, and I continued my quest.

After resuming the piano, it took more than 20 years to learn various piano playing techniques,After a miraculous encounter, the gloomy feeling gradually cleared up.

Finally, in June 2022, it was mastered, and in September, it evolved through a mysterious experience.I was able to complete the ultimate "Oxytocin playing method", which can be said to be the essence of piano playing that has never appeared on the stage until now.

Thank you for the "Cococal Chorus" course the other day.

It was a very enjoyable and fulfilling day as the course was very informative and the content of the course was very detailed as he carefully taught me how to play.

Personally, I feel that the playing style that you taught me is not completely different from the way I have played so far, but it is more simple as if I were to remove the extra parts of my playing style. I felt like I was getting lighter.

There are moments when I feel very comfortable and beautiful while playing, and it is very comfortable.

There were many things that surprised me about tuning, and it was interesting to see the difference in how sounds are perceived depending on the tuning.

I listened to sounds that were tuned to a pleasant sound for a while, and then when I listened to the sounds of unsettling tuning, my head hurt a little and I felt nauseous. It's just

After taking the course, the feeling of playing changes every time you practice, and sometimes you suddenly notice that the feeling of playing improves.

For example, when practicing using yurumu kotoba, it's easier to play by actually feeling "the state of being already" instead of just saying it.

By doing basic practice slowly and carefully, it can lead to realizations, so I think it's important to keep working hard every day in many ways.

Thank you very much for allowing me to participate in this class in a warm and friendly atmosphere from beginning to end.

It was really fun to learn about a new world of sound and experience it with all five senses.

Mr. H from Nagoya

I stopped playing the piano when I took university entrance exams. After growing up, I wanted to play the piano again, so after a few years of hiatus, I resumed playing the piano.

Piano is really fun and I have met many wonderful musicians through music.

I learned how important teacher selection is.

For this reason, I had a strong will to only be taught by a teacher whom I was satisfied with.

It is said that the best way to get things done is to learn from an expert in the field.

Conversely, if you choose the wrong specialist, you may end up taking a detour.

I wanted to know the fundamentals of piano.

In the meantime, 20 years had passed since I resumed playing the piano.

After attending Sugimaru's course the other day, I feel like I understand why I haven't studied under him for 20 years.

It was just like connecting the dots.

I was deeply moved by the fact that I wanted this for the piano, to which I had devoted most of my life.

They say that the important things are simple, but even though it is simple, it took me 40 years to learn it for the first time.

If you want to know the essential performance techniques of piano playing and the infinite power of music, please take this course.

Your piano life will change forever!

I think the two days were a series of discoveries and integrations.

I knew very little about tuning, so I was often surprised.

Isn't this something that can be taught outside of this course? I thought.

You will be able to understand things that you have known by chance until now, such as the difference in dynamics between ⚪︎⚪︎ and how to play from the ⚪︎⚪︎⚪︎ keyboard. This sense of integration, which had been vague, was cleared up and led to a deeper understanding.

In addition, I was given enough time to practice, so I was able to acquire basic playing techniques. I'm here.

I'm really glad I trusted my intuition and took the course.

thank you very much.
