"Architecture is solidified music", which is a famous saying praised by countless philosophers. Goethe, Hugo and Beethoven all called architecture "solidified music", not only because of the wonderful legends about the relationship between music and architecture in ancient Greece, but also because of their similarity and correlation. Although different arts have their own characteristics, they are internally related, which enables artists to get inspiration from different arts and makes it possible for various arts to "transplant" and merge with each other. Comparing architecture to solidified music means that if the time flow of music is completely solidified, we can see the modeling characteristics such as strict mathematical proportion, symmetry and balance, and the connection between music form and architectural structure from music or music score. The combination of building materials that conform to laws and regulations can give people the beauty of rhythm and rhythm. Architecture is a kind of space plastic art, but it also has some characteristics of time art, because architectural space is often a spatial sequence, which needs to be gradually spread out in motion and placed in a time-shifting sequence to appreciate its full charm. The development of spatial sequence not only reflects the simple and clear rhythm through the continuity and repetition of space, but also reflects the cadence rhythm through the regular changes of height, fluctuation, shade, density, reality, advance and retreat, interval and so on, which is quite similar to the overture, expansion, crescendo, climax, repetition and pause in music, and can give people an exciting sense of melody. The Forbidden City in Beijing, from Zhengyang Gate, Duanmen Gate, Wumen Gate and Taihe Gate to Taihe Hall, Baohe Hall, Zhonghe Hall and Jingshan, stretches along the central axis of Qili, with more than a dozen courtyards criss-crossing, prelude, gradual strengthening, climax and binding. Hundreds of halls are strewn at random, with main body, background and contrast. A magnificent spatial sequence is like a group. China's four ancient echo buildings, each with its own characteristics, are world-famous. They are very musical buildings, shining with the wisdom of the working people's musical talent in architecture. The echo wall and the three-tone stone in the Temple of Heaven in Beijing in the Ming and Qing Dynasties are fascinating, and the inner wall of the echo wall is smooth and flat, which makes the external sound pass along the inner arc and reverberate for a long time. If you stand in front of the wall and hum gently, the harmony will rise, deep and tactfully, and the expression will be beautiful; If you sing loudly, the echo will be everywhere, loud and rough, lingering in your ears and shocking. The Toad Sound Tower in Shan County, Henan Province was built in the Kangxi period of the Qing Dynasty. Although the tower is not high, it is famous for its "amazing sound". If tourists hit the tower with their palms, it will make a "giggle" sound, just like thousands of toads singing in their eardrums. In ancient foreign buildings, there are also famous "musical" tower buildings, such as the bell tower of Pisa church in Italy. The top of the tower is equipped with seven graduated clocks, which can emit seven sounds of "do, re, ml, fa, sol, la and sl". It is an interesting "music tower". The leaning tower of Pisa belongs to the bell tower of Pisa Cathedral. Whenever a church ceremony is held, the clock on the tower will give out beautiful music. There is a "music staircase" in an ancient temple in Tamil India. When you step on the stairs or tap with wood, you will make different pitches. This staircase is repeatedly processed with granite of different materials and built in different positions according to the law. There are not only music towers and ladders, but also bridges where music can be played. Toyota in Japan has a 3 1 meter long pedestrian music bridge. There are 109 audio railings on both sides of the bridge. Pedestrians can play a French folk song (on the bridge) by tapping on the railing in sequence, and a Japanese folk song (hometown) by tapping on the other side. With the development of electronic technology, the combination of architecture, music and electronic technology can create a trinity building. The music magic wall in Marseille is an example. 1984 In March, the second subway in Marseille was opened to traffic, and a pile of magical green walls began to meet the public in the Castellana subway. When people pass by it, it will emit waves of music accompanied by the rhythm of pedestrians' footsteps. It turns out that this is an unusual magic wall-the music wall. Music wall plays music with the help of the computer, and the memory of the computer stores all kinds of basic notes and short sentences, forming a composition system. When pedestrians pass the music wall, they change the light intensity of the photocell. This information is received by the computer, and after special program processing, it becomes a set of music prepared according to the action of pedestrians crossing the wall. Pedestrians are both players and appreciators of music. In addition to the magic wall of French music, American parks and playgrounds also have interesting "music floors". With the development of economy, people's living standards are constantly improving. People love beauty, pursue beauty and are eager to enjoy beauty. Music beauty and architectural beauty are important parts of modern life beauty. In architectural design, the architectural art laws such as theme and image, unity and balance, contrast and harmony, proportion and scale, rhythm and rhythm, repetition and change, personality and style, color and tone are emphasized, which are closely related to the artistic laws of music creation in terms of aesthetic information. If architects can know more about music and improve their artistic quality and accomplishment in an all-round way, they will gain more freedom, more beneficial enlightenment and wonderful inspiration in architectural creation and design. Goethe, a great German poet, said that when he walked on the colonnade in front of the Roman Cathedral designed by Michelangelo, he deeply felt the melody of music. Liang Sicheng, an architect from China, also wrote a silent movement for the Liao Dynasty brick tower facade of Tianning Temple in Beijing, and he also found a harmonious rhythm from the promenade of the Summer Palace. Standing at the top of Jingshan Mountain overlooking the Forbidden City complex, along the central axis, you can see the theme melody and counterpoint of the symphony in China's ancient buildings. Music and architecture are different kinds of art, although they are different disciplines, but the two philosophical words "Music is a flowing building" and "Architecture is a solidified music" really vividly reveal the close relationship between music and architecture, as well as the aesthetic information, laws and profound connotations.
