"Music is the science of the heart."
Fibonacci Sequence


Science has everything to do with music due to the law of physics. Music is produced when you apply tension or force to the instrument, therefore it must obey to the law of physics.

When playing an instrument, you are applying certain pressure to that area to create the specific sound you want. It's the same when you're singing, you are using your vocal chords to hit those notes, but in order to get a clear and precise on, you have to breath from your diaphragm.

How do we hear the music?


The instrument creates sound waves which produce vibrations that go through our eardrums while reflecting its aids so we can listen to the glorious music we all know and love. Not only do vibrations cause sound we can hear but it can cause the change in pitch and volume.


this is a well known sequence that follows as: 1, 1, 2, 3, 5, 8, 13...

How does this relate to music?
In music, the fibonacci squence can be seen in piano scales. They utilize the same pattern
From chord progressions, rhythm, beat, to emotions and chemical reactions in our body--interestingly enough, they all connect with Math and Science!
Fractions
Both music and mathematics use fractions and numbers
-music uses fractions and numbers for various rhythms.
Sources
Notes in music also represent different fractions, which then represent rhythms.
Music has been the source of research in many areas of math such as:
Abstract Algebra
Set Theory
Number Theory
Research has shown that certain pieces of music become more popular and mainstream to their "Mathematical Structure"
Music with repetitive structure becomes more popular because it has rhythmic beats and looping breaks!
How We Interpret Music
This is due to our innate mathematical need for rhythm and patterns...
Jason Brown, a professor of mathematics at Dalhousie University used a mathematical tool called

The way we music affects us involves both psychology and biology.
"Fourier Transform"
Biologically, listening to music can change the brain activity by stimulating the nucleus accumbens. Which is a part of are brain that controls when and where we feel pleasure.
This technology was used to analyze and solve decades-old mystery and notes of songs.
Particularly the song:
"A Hard Day's Night" by The Beatles
tempo
On the psychological side, after listening to music our brain releases dopamine. Which is a chemical our brain produces that makes us feel what we call happiness.
The mind-body connection between music and math have sparked continuing debates surrounding the so-called

Time is often used in music to measure different tempos.
(speeds)
This is usually done through metronomes with different time markings.

This was popularized in the 1990's. It is believed that students do better due to the exposure to Mozart
Music relates to chemistry in many unique ways. The two most obvious ways are how they both use their own specific systems.

- music has a system of notes and notations
- science (mostly chemistry) has the system of elements and formulas

Music and science both use mathematical principals and logic as well as "formulas" and "theories" to solve scientifical and mathematical problems.
Last, beats and timings deal with wavelengths too, that is how music manages to influence people.


There are also several scientific theories that all try to explain music.
An example is a theory called "science of music".
This theory states that each musical note interacts with another note in an exact way to make a certain sound.


It is also know that the nucleus accummbens contributes to the regulation of emotions through music.
For example, a quarter note is 60 seconds in common time, while a eighth note is 30 seconds and so on.
Examples of links between physical practice of music and strong abilities are the following:
Kids who play a music instrument can perform more complex arithmetical operations than those who don't
The slow-work of practice, the attention to detail and discipline it takes to learn an instrument are excellent preparation for the practice involve building strong math skills
Research shows that children who learn their academics through music and dance retain information better

In music there are different scales using different patterns.
Science

Math is used for:
chords
time signatures
dotted half-notes (representing a count of 3)
Not only can music change our mood, it can can help with emotional illness. It is proven that music therapy can help tremendously. It can be used for pain relief, anxiety, and stress reduction.

Did you know that theorists sometimes use math to understand music?
Math and music have a big connection
Intervals
Intervals are the difference between notes.

Not only this, but ratios are also used for these intervals in musical passages.
For example: a perfect 5th has a ratio of 3:2
Shapes of instruments
instruments are differently shaped to produce different sounds.

How they figure this out is by mathematical calculations that would measure the various sound waves and pitches produced.

Finally, music always has an effect on the human brain. If any type of music doesn't affect someone, it most likely means that person is dead. Anyways, according to my research, there are many studies that have shown:

-music gets the brain to wake up
-while listening to music the brain begins to pay attention and make predictions.
-music can easily have an effect on one's mood depending on the type
-music that makes a person happy releases a chemical called "dopamine" which is usually released when someone is in pleasure
-the part of the brain that positively reacts to music is called the "nucleus accumbens"
-if the brain positively reacts, the person is usually more likely to listen to that song repetitively

Overall, music helps scientists understand the complex functions of the brain. There are different reasons as to why each person likes their own genre of music but no matter what, in the end the brain will react and give either a thumb up or thumb down.
