Great interest in Setar lead him to Hossein Alizadeh, and in fact his artistic promotion is indebted to this valuable master of Iranian music. As to the fact that, in his childhood, he had also been trained by some outstanding masters such as Hormozi and Forutan, managed to become fully familiar and accustomed to Iranian classical music and discovered its delicacies and beauties. Shaari has always tried to reconstruct the works of the pioneer masters of music and this high goal resulted in creation of two albums, "Shabahang" and "Karevan-saba".

 In Shabahang we can see improvisation in Radif (Iranian traditional  music systems), and also reconstruction the works of some masters as Roknneddin Mokhtary, Saba, Hormozi, and Forutan. In Karevan-Saba, the chief goal is interpretation of some pieces of music for setar, originally composed by master Saba for violin. 

 Shaari has always endeavored to teach Iranian classical music and has been involved in Setar tuition since 1981 in art centers directed by private and public sectors. In this connection, he has trained many apprentices following his artistic school. Now, he teaches privately, as well as in Azad University, and artistic center of Kamkars Ensemble. He follows his special teaching method (which is under publish.)
Massoud Shaari, with his complete control over traditional Persian music, has tried to restore the almost forgotten melodies and rhythms of traditional Persian music, and confront it with contemporary music and modes of interpretation.
 It seems that his insight of music is absolutely free, and he tries to restore the lost elements of Iranian music such as forgotten rhythms and melodies, and mix them with modern music.
 For the past ten years, he has been teaching Setar and theory of traditional Persian music in different places: Azad University, “Kamkar” musical center, and in various other musical centers in the private and public sectors..
