ehrouz Mohammadi, “Daf and its feasts in Ghaderieh’s Tekyeh” mentions that the outer thickness of arch where studs are located, [is] between one to one and a half centimeters (Mohammadi, 2001: 12). The thickness of arch should be gradually reduced from the installation place of rings to skin (Avazeh of Daf) to create a high volume, clear sound from Daf; also, the connection of arch to skin should not be less than one millimeter, because in this case the skin will be torn due to the sharpness of the wood (Mogharab Samadi, 2009: 79-78). The thickness of wood on the skin side is about two to three millimeters (Tohidi, 2002: 79).

Regional music festivals are organized to, firstly, introduce the music of different regions and, secondly, to support its performers. Regional music festivals are held in large cities for various reasons, including the availability of financial and executive facilities and the presence of an audience. However, the organization of these festivals has always been one of the challenging issues of ethnomusicology. The reason is that the presence of regional music performers in large cities places them in a context other than the context they would normally perform in their homes; consequently this change in situation leads to changes in the quality of their performance.

One of the most important criteria for measuring the quality of a piece of classical music is number of times the piece has been performance by different ensembles and orchestras in different eras. This belief has become so pervasive in some societies, such as Iranian society, that it is considered the only criterion for measuring the quality of a piece of classical music.

Iranian pianist Layla Ramezan has always sought to create a connection between her Persian origin and the contemporary music which she encounters daily. Sound, phrasing, a particular sense of rhythm and a refined understanding of the “time of musical development” are the foremost qualities of her interpretations.

Having moved to Paris and received a scholarship from Albert Roussel Foundation, she integrated the classes of Jean Micault and Devi Erlih at the Ecole Normale de Musique de Paris Alfred Cortot, where she received a Diplôme de Virtuosité in piano performance and chamber music.

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.
