Naser al-Din shah Qajar traveled to Europe three times During his reign,  (1290 A.H / 1872 A.D - 1295 A.H / 1878 A.D - 1306 A.H / 1888 A.D), and was greatly influenced by European culture and developed a culture of Normal. The question is what was the impact of his observations from the west on the art of this period? He partly was familiar with aspects cultural- art in Europe, after the return, ordered to imitate the West artistic styles especially in the field of music and drama and it was while the court of Nazareth had different kinds of art in music and drama But in a short time, most of these groups, or the king wanted to imitate Western methods or the court rejected and turned to run between laymen, and their successor were Dar ul-funun  music band led by monsieur Lemaire and Dar ul-funun dramatic band led by Mozayan al-dawla, Although the latter group activity was also associated with contraction and expansion. The present study aims to investigate the process of Naser al-Din shah trips to the West and its impact on the Iranian art, especially in the field of music and drama, and scrutinize and analyze the course of transmission the West art features in two traditional art by the descriptive-analytical method and based on recent research. The findings argue that although was created innovations in the two aforesaid fields of art, but many of the Iranian old styles_such as Naqareh-khaneh and court groups of display_were forgetten and on the one hand, and Western styles in the field of music (using items such as solfège, harmony and orchestration) and display (such as plays, venues and social content) in advance welcomed and considered.. which its reason was greatly in bilateral westernization of the Naser al-Din Shah and many of the artists of the period.
