Architecture and music are two artistic fields that are created and understood by humans. Music is the emanation of human feelings and thoughts and an expression of his inner states, and architecture can be called solid music, because it can display the same feelings and thoughts in a body of materials. Music becomes more meaningful in the dimension of time, and architecture in the dimension of space. All arts ultimately open a path to abstraction and experience, so many similarities can be found between architecture and music because in the creation of architecture, the artistic imagination and mental forms of the artist reach the border of abstraction through the element of ambiguity that results from the use of symbols of objective forms in the construction of the building, where music has a high position. The issue that this article has addressed is the most obvious and important aspect of the connection between these two arts, which provides a deep relationship between these two arts, and that is the practical and aesthetic considerations of these two arts. It is as if there was something in the mood and quality of the spaces of music and architecture of the past that has changed today. The aim of this article is to examine the historical and evolutionary course of the conceptual connection between these two arts, that is, to examine order in music and its place in architecture.
