As a very familiar art category, music is often closely related to our lives. The great inclusiveness and possibilities it has also made people start to explore the cross-field application of music very early.
In 1940, during the rapid development of animation, in order to make cartoons become an art shared by the commons from a popular culture, Disney founder Walt Disney first thought of combining classical music with fantastic cartoon animation. Thus was born the classic animated feature film Fantasia.

Fantasia is based on seven classical music works, including Beethoven's Pastoral Symphony, Tchaikovsky's The Nutcracker and other world-famous pieces. In order to help children better understand these classical music when watching animations, it takes a lot of effort to make cartoons.
For example, in "Pastoral Symphony", the cute animals that children like more are used to tell the story, unicorns, pegasus, etc. fly in the sound of music, and pairs of half-orcs live a pastoral life, a happy and peaceful scene.
At the same time, the image of the god in the Greek fairy tale is used to express the powerful part of Beethoven's music, and with full imagination, the picture corresponds to the music.
In 2000, Disney launched a sequel, "Fantasia 2000", which also left a lot of classic pictures. Among them, impressively, is the Animal Carnival adapted from the works of the composer Saint-Saëns. Pink flamingos play yo-yo to the rhythm and are very fun.
Of course, this picture is not just for fun, but also tries to help everyone appreciate and understand the rhythm changes in the music through the game of flamingos, and understand the difference between the single line and the multi-voice part of the sound: when a flamingo and a group of flamingos are tied by the rope of the yo-yo, the acoustic effect is different.
"Fantasia" combines music with new and interesting animation, which has become the enlightenment of classical music for many people, and at the same time, it also makes us feel the other possibilities of music.
With the development of the Internet and science and technology, we have seen more and more music across fields and disciplines, which are very creative and refreshing.
On the tubing, the "sliding line riding" series of videos created by the god DoodleChaos once detonated the whole network. DoodleChaos is a music physics enthusiast who likes to study some physics-related synchronous chain music experiments. He combines physics with music, visualizing music with line animations.
DoodleChaos's earliest work in the circle was "Blue Danube" expressed by the gliding villain.
You can feel it, the gliding little people with the rhythm of the music, sometimes lively and cheerful, sometimes slow and melodious. The trajectory, time, speed and melody of the little man's action are completely consistent with the musical melody, and are also completely synchronized with the beat and pause of the music; every time one more instrument sound appears in the music, one more little person will join the gliding together, and the high and low of the musical mood can be expressed by the ups and downs of the gliding line.

In this combination, music gives animation rich emotion and strength, and the visual stimulation brought by animation further enriches the music, and every frame can bring surprises.
After the Blue Danube fire, DoodleChaos continued to experiment with the gliding villain. He once used 8 gliding villains with William Thiel overtures, incorporating the concept of competitive competition, and only one of the 8 villains finally managed to reach the finish line. The process is full of suspense, and the music is full of infinite fun by relying on such an exciting competition.
Not only that, but DoodleChaos also created "domino music" that completely coincided with Tchaikovsky's "Flower Circle Dance".
As the music progresses, the dominoes emit corresponding sounds, and each melody, pause, and twist can find the corresponding movement action, which is very wonderful.
Of course, in addition to visualizing music, the knowledge of many other disciplines can also be expressed in music through cross-disciplinary methods.
The "π" in mathematics should be familiar to everyone, right? As we all know, this is an infinite non-looping decimal, and many people are proud to remember the last few decimal places when they are young. But have you ever imagined what it would be like to compose Pi into a song?
The composer Michael Blake translated the first 31 digits of pi into notes, and he used the concept of chromatic scale introduced in the law of twelve averages to correspond the chromatic scale to the numbers one-to-one, that is, 1 = C, then 3 = D, 5 = E, 6 = F, and so on, composed into a tune. A simple piano melody is introduced, and instruments such as xylophone and accordion are added to make the melody sound richer. While enjoying the beautiful melody, you can't help but sigh that mathematics can be so beautiful.
If food could have a sound, would you like to know what kind of song you eat every day?
Yes, diet can also be expressed in music. A fast food restaurant in the United States invited a special music producer to give more than fifty kinds of food different instrument sounds, such as avocado is a violin sound, chicken is a bass sound, each choice of ingredients, there will be a corresponding instrument playing sound, and finally combined together, eat a meal can enjoy a strange symphony.
Since then, eating has become a unique enjoyment, and choosing a meal has become a musical experience and challenge.
At the beginning of 2020, the new crown virus spread around the world, and to this day, the situation is still grim. In order to improve everyone's understanding of the virus, scientists have used audible technology to compose a tune for the new crown virus so that people can hear the virus.
The researchers used different notes to represent the different amino acids that make up the structure of the new coronavirus spike protein, and then used different lengths and strengths of music to express different structural characteristics such as spiral or flake shapes of amino acids, using instruments such as flutes, bells, and Japanese thirteen strings to compose a musical score of nearly two hours.
I believe that in the imagination of many people, the music written with the structural characteristics of the new crown virus must sound very painful, but in fact, this music in the initial stage, it sounds a little beautiful and soothing. This just reflects the ease and simplicity of the new crown virus entering the human body at the beginning, and as the virus lurks longer, the music enters the second half and begins to become violent and turbulent, symbolizing the extremely destructive power of the virus.
Composing viruses into music, on the one hand, can help ordinary people to understand them more intuitively; at the same time, it also makes us feel that human beings in the face of disasters, the pursuit of art, such a romantic and optimistic spirit, is our weapon and strength to overcome difficulties.
Finally, what other knowledge can be expressed in music? Welcome to leave a message to share with you ah~
