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).

Gholam Reza Khan Minbashian, a.k.a Salar-Mo’azez, was a pioneer in several domains in the history of the Iranian music. He is recognized as the first Iranian musician who was educated in classical music. He is also the first Iranian the score of whose works were published in Europe. He is the first Iranian to have launched courses on Western classical music and was also the first Iranian teacher of classical music. Moreover, he is the first founder of a string orchestra in Iran, the first author of the Iranian Radif which was available in oral form. Minbashian is also the first Iranian who studied music in Europe.

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.

At the end of the Qajar era and as Iran entered the power transition period, known as the constitutional era, the Iranian music went through a lot of changes. These changes gained momentum as the students and followers of Ali Naqi Vaziri’s entered the musical scene. These changes greatly influenced designs of instruments, playing methods, singing, composing, etc.

Today, percussion instruments have such a high place in music that are an essential element of orchestras. This has attracted many people to this type of instrument with roots as old as the first humans. A historical study of music, shows that humans used the sound of these instruments to defend themselves against wild animals and, over time, for alerting each other, signaling their readiness and encouraging people for war, ritual ceremonies, dances, etc. in a manner that is still clearly visible in music and some ritual ceremonies.

In the world music culture, there are instruments which were traditionally associated with a certain gender. It remains disputable to what extent these gender-based perceptions have been logical and scientific. For example, as playing wind instruments need more breath strength and the public opinion believe that men have stronger breath compared to women, these instruments are predominantly a male domain. Harp is also considered a female instrument as the public opinion believe that women have finer fingers and can therefore better perform nuances and delicate techniques on the instrument.

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. Her musical and pianistic education began in Tehran at the age of 8 with Mostafa-Kamal Poortorab. 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.

Davoud Pirnia, writer and musicologist was the founder of “Golha” (Flowers of Persian Song and Music) programs on Tehran Radio (1956-1966). He received his early education from his father, Hassan Pirnia (Moshir al-Douleh), and several tutors of the time (Taraghi, interview, July 1989) and continued his studies at Saint Louis School in Tehran and then in Switzerland and graduated in law. While studying law, Pirnia got acquainted with European classical music. Upon returning to Iran, he was employed by the Ministry of Justice and founded the Lawyers’ Guild. Then he was transferred to the Ministry of Finance and established the Department of Statistics in this ministry. Later, he became the head of the state inspection office at the Prime Ministry; he was, then, promoted to the position of the Deputy Prime Minister (Navab Safa, interview, August 1999)
