Iranian classical music uses 12 modes, namely 12 kinds of "Dastgarh", among which Shure, Mahul, Homayun, Se Garh, Chahar Garh, Nava, Rast-Panji Garh are regular modes, while Dashti, Abu Atta, Bayat-Tork, Afshari and Isfahan It is the submodal mode, which is derived from the positive mode and is called "Avaz". Iranians believe that each of these modes expresses different emotions. For example, the Nahua mode expresses peace, the Homayun mode expresses happiness, and the Segah mode expresses pain and sadness.

There are also 12 sets of "Dastgarh" as a performance form and musical genre. The performance of "Dastgarh" is highly improvisational. It usually takes 30 to 45 minutes to perform a set of "Dastgarh", which can also be as long as one hour, or can be shortened to 10 minutes. Regardless of its length, each set of "Dastgarh" must include four parts, starting with the scatto overture "Dalamad", followed by "Asle Awaz", "Talanif", It ends with "Lange". The beginning and end of each set of "Dastgarh" uses the same mode, and this mode name also becomes the title of the set of music, such as "Nawadastgarh", "Shuldastgarh", etc. The connection between the various parts is composed of various stylized tunes "Guxie", and "Guxie" can use other modes. For example, in "Schuldastegach", when playing "Gushe", you can change fa to fa sharp, which will cause a variation in the modal color. "Gushe" can be long or short. Sometimes it is named after a region, such as "Rebr Gushe" and "Ravandi Gushe"; sometimes it is named after a person, such as "Humayun Gushe" and "Manyi Gushe". All "gushes" used in the 12 sets of "Dastgarh" are collectively called "Radif". Learning to play "Gu Xie" requires high skills and innovative spirit. Iran's traditional singing method is quite special. A method of alternating true and false voices called "Tahriel" is commonly used in singing.
