The importance of proportion in architecture and music with a Focus on Plato Thoughts

The existence of rhythm, harmony and symmetry in architecture and music shows us, these two artists have a lot in common. The buildings left from ancient times to the buildings that exist today; They express a conceptual connection between music and architecture, and it can be said that both arts have been the messengers of single concepts at any point in time. This connection is so much that some have mentioned architecture as frozen music.  These links have connections and points of commonality that these similarities and commonalities can be defined and categorized in these categories. Physical, visual, conceptual, epistemological, functional, aesthetic, structural, cultural, contextual... The purpose of this research is to find the connection between Plato's views and the aesthetic commonalities of music and architecture. The main research question: Is it possible to find commonalities between architecture and music according to Plato's views? There is no specific hypothesis in this research and answering the question cannot be considered as a novel hypothesis. This research has been carried out using a descriptive analytical method. The relativity of ideas and differences of opinion is one of the biggest obstacles and limitations of this research. Seyyed Baqer Hosseini in an article called "Mental pattern: the product of the interaction between music and architecture design" in Abadi magazine, year 19, number 64, page 123-125-126, deals with the proportions of music and architecture.
