Despite the fact that Iranian folk music (regional music of Iran), like the Radif of Iranian traditional music, is monophonic and follows heterophony in principal, we experience polyphonic forms, albeit, majorly unconscious.

Mohsen Renani in the preface of his book entitled “The Political Economy of nuclear conflict; an introduction to traversing the civilizations” writes:

Joint application of the two techniques of “Lip” and “Nose” could be effectively applied for hearing and playing far-away intervals, by the Classical Guitar. Before this, a Classical Guitar player had to waive playing intervals not possible with the left hand, and had to replace or eliminate some notes, making it possible to play such intervals; specifically the capability of the left hand of the musician, was also a factor in such a selection. These methods are hereby illustrated by photographs and a video-file, in order to provide optimum comprehension of applying these methods, invented by the author; specifically the “Lip” technique, which is considered to be a more significant technique, emphasized by the author.

Ashura Opera was composed by Behzad Abdi, the Iranian composer, in 2008 based on librettos compiled by Behrouz Gharib. The main source for the libretto is poems by Mohtasham Kashani, a sixteenth century Iranian poet.

With its simple physical structure and captivating sound, the Daf never belonged to a particular culture or location, and every nation had different usages for this instrument considering their dominant customs and traditions.

Music as an art has its own special history; emergence of a singer, of an instrumentalist and then the emergence of the strong character of a composer covers three significant phases of the art of music. With the emergence of composer which was simultaneous with the emergence of the language of music, this art managed to offer a domain for criticism for its composer; a procedure which led to a magnificent variety and evolution in musical production. Even though the conflicts between singers and instrumentalists have not met their end in the Iranian society and while singers can achieve high, instrumentalists have yet to play behind curtains . In a special era, with the efforts of musicians such as Ali Naghi Vaziri (1887-1979) and Rouhollah Khaleghi (1906-1965), glimmers of a composing era started to glow bearing fruit in Khaleghi’s achievement as Iran’s first professional composer. Khaleghi made his reputation as a composer while Vaziri deserved to pioneer this path. By then Vaziri was well-known as a Tar player.

One of the most popular terms used by Iranian instrumentalists is the existence or a lack of musical “sense”. Both musicians and fans of music consider having “sense” while playing music as an important principle to the extent that they use it vis-a-vis having technique.

Shaahin Mohajeri, the award-winning Iranian microtonal compose, has contributed to The Art of Silence is an international project which features unpublished pieces by microtonal composers from Iran, Japan, the United States, and other countries.

Regarding the classification of a new instrument in an instrument family, one can point to a number of fundamental issues, one of the most obvious of which is the instrument’s visual features. If we look at how the new instrument has changed compared to its historical versions, the set of visual elements that link the instrument to the Qeychak family becomes apparent. But other characteristics such as the geometric dimensions of the instrument, characteristics of the instrument’s various parts and how they relate to each other, its systematic performance, its sound range (compared to modern versions), the material and color of the sound, the way it is played and the like, can be considered in order to classify the instrument in the Qeychak family.

The term “School of Vaziri” is often used in writings on Iranian music, but the exact meaning of the term is not clear; some of the authors have used the term to only refer to the group of Vaziri’s students, including a large group of his conservatory students and his Tar students such as Abolhassan Saba, Rouhollah Khaleghi, Ahmad Foroutan Rad, Hossein Sanjari, Heshmat Sanjari and others. But can we consider all Vaziri’s students as followers of his school of thought? This is definitely a mistake, because we know that some of Vaziri’s students have chosen a completely different path than that of Vaziri.
