Did you know that every time musicians pick up their instruments, there are fireworks going off all over their brain?
2
On the outside, they may look calm and focused, reading the music and making the precise and practiced movements required.
3
But inside their brains, there's a party going on.
4
How do we know this?
5
Well, in the last few decades, neuroscientists have made enormous breakthroughs in understanding how our brains work by monitoring them in real time with instruments like fMRI and PET scanners.
6
When people are hooked up to these machines, tasks, such as reading or doing math problems, each have corresponding areas of the brain where activity can be observed.
7
But when researchers got the participants to listen to music, they saw fireworks.
8
Multiple areas of their brains were lighting up at once, as they processed the sound, took it apart to understand elements like melody and rhythm, and then put it all back together into unified musical experience.
9
And our brains do all this work in the split second between when we first hear the music and when our foot starts to tap along.
10
But when scientists turned from observing the brains of music listeners to those of musicians, the little backyard fireworks became a jubilee.
11
It turns out that while listening to music engages the brain in some pretty interesting activities, playing music is the brain's equivalent of a full-body workout.
12
The neuroscientists saw multiple areas of the brain light up, simultaneously processing different information in intricate, interrelated, and astonishingly fast sequences.
13
But what is it about making music that sets the brain alight?
14
The research is still fairly new, but neuroscientists have a pretty good idea.
15
Playing a musical instrument engages practically every area of the brain at once, especially the visual, auditory, and motor cortices.
16
As with any other workout, disciplined, structured practice in playing music strengthens those brain functions, allowing us to apply that strength to other activities.
17
The most obvious difference between listening to music and playing it is that the latter requires fine motor skills, which are controlled in both hemispheres of the brain.
18
It also combines the linguistic and mathematical precision, in which the left hemisphere is more involved, with the novel and creative content that the right excels in.
19
For these reasons, playing music has been found to increase the volume and activity in the brain's corpus callosum, the bridge between the two hemispheres, allowing messages to get across the brain faster and through more diverse routes.
20
This may allow musicians to solve problems more effectively and creatively, in both academic and social settings.
21
Because making music also involves crafting and understanding its emotional content and message, musicians often have higher levels of executive function, a category of interlinked tasks that includes planning, strategizing, and attention to detail and requires simultaneous analysis of both cognitive and emotional aspects.
22
This ability also has an impact on how our memory systems work.
23
And, indeed, musicians exhibit enhanced memory functions, creating, storing, and retrieving memories more quickly and efficiently.
24
Studies have found that musicians appear to use their highly connected brains to give each memory multiple tags, such as a conceptual tag, an emotional tag, an audio tag, and a contextual tag, like a good Internet search engine.
25
How do we know that all these benefits are unique to music, as opposed to, say, sports or painting?
26
Or could it be that people who go into music were already smarter to begin with?
27
Neuroscientists have explored these issues, but so far, they have found that the artistic and aesthetic aspects of learning to play a musical instrument are different from any other activity studied, including other arts.
28
And several randomized studies of participants, who showed the same levels of cognitive function and neural processing at the start, found that those who were exposed to a period of music learning showed enhancement in multiple brain areas, compared to the others.
29
This recent research about the mental benefits of playing music has advanced our understanding of mental function, revealing the inner rhythms and complex interplay that make up the amazing orchestra of our brain.

このレッスンについて
このレッスンでは、楽器演奏が脳に与える多くの利点を学びます。音楽の演奏がどのようにして脳の複数の領域を活性化し、思考力や記憶力を向上させるのかについて掘り下げます。また、英語でのコミュニケーションを改善するために、この情報を通じて語彙を増やし、発音を向上させる方法を練習します。特に、英語スピーキング練習やIELTSスピーキング対策に役立つ内容が含まれています。
重要な語彙とフレーズ
- 楽器演奏 - Playing an instrument
- 脳の処理 - Brain processing
- 神経科学者 - Neuroscientist
- 情緒的内容 - Emotional content
- 記憶機能 - Memory functions
- コーポラス・カロサム - Corpus callosum

練習のヒント
このビデオのスピードに合わせて、英語の発音を良くするための効果的な方法は、シャドーイングです。特に、楽器演奏に関する部分を繰り返し聴きながら声に出してみましょう。以下のポイントを参考にしてください：
- テンポを保つ：ビデオの音声と同じスピードで発音できるよう、何度も繰り返して練習しましょう。
- 感情を込める：楽しくリズムに合わせて声を出すことで、より自然な発音になります。
- 音を切り取る：語彙やフレーズを少しずつ聴き、音を真似する練習を行いましょう。
- 反復練習：重要なフレーズを繰り返すことで、記憶の定着が助けられます。
この方法を用いることで、英語スピーキング練習がより効果的になり、コミュニケーション能力の向上につながります。特に、神経科学者が発表した研究に基づく音楽の利点を実際の英語学習に活かしましょう。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
