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).

Torqeh or jal is the same bird (Bimaculated lark) and is the name of a muqam which is well-known in Torbate Jam and those areas. Jal muqam is called Torqeh in Esfarayen and Bojnourd. This muqam which was used to be played by Bakhshis/Bagşies (dutar-players) in the past is seldom performed today.

This year marks the fifth anniversary of the passing of Khosrow Jafarzadeh (Khosrow Djafar-Zadeh), a distinguished architect and pioneering researcher of Iranian music, whose contributions to the magazine “Harmony Talk” have left an indelible mark on the field. The absence of this remarkable individual has significantly impacted the expansion and advancement of his theories, which are heralded as some of the most progressive in the history of Iranian music

Developments in Composing

Along with developments in the Iranian instruments, composition of the Iranian pieces developed as well. As a matter of fact, the developments of the two, mutually affected each other. In other words, instrumental developments led to developments in composition and vice versa.

Creating sound continuity between two notes in the source and destination positions when left hand position changes and “two different finger numbers” are involved is called portamento. Portamento can be performed on single string or two neighboring strings and with hand moving on fingerboard either upward or downward.

The perspective that denies any alteration or innovation beneath the realm of Iranian music, and more broadly, the performance and even the structure of Iranian music instruments, stems from the discourse of “tradition-oriented”* and the “return to self” movement in Iranian music. Given that some educators still adhere to this discourse and emphasize the necessity of preserving tradition, a perception is formed among art students that Iranian music, including Radif, lacks dynamism and is confined within a rigid framework.

April 6 marks the anniversary of launching HarmonyTalk.com. Back in 2004, HarmonyTalk was rather a blog dedicated to music. Gradually, however, it found its way to becoming a more sophisticated journal with an intensive but not exclusive concentration on classical music.

With this description, we have automatically included a criterion called “History”, Until we know the time of the creation of a work of art, we cannot judge whether it has been easy to create or not. Suppose that, in a historical study, we find a musical work that is similar in compositional techniques (including form, melody, context, and orchestration) to a minor work of the nineteenth century; however, our research proves that, this work dates back to 200 years prior to that date. Can we still consider this work insignificant? Definitely not! So this is where the first use of history-based judgment comes into play.

With regard to each polyphonic form, only one specific and distinguished example is analyzed. These polyphonic forms are as follows:

Bahman Rajabi, the renowned tonbak (Persian goblet drum) player and educator, passed away at his home at the age of 86 due to a heart condition. He was the founder of a distinctive school of tonbak playing, and his teaching methods have been widely used by instructors of the instrument for decades..
