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).

On the 10th of Khordad, 1403 (equivalent to May 30, 2024), the twentieth anniversary celebration of the online journal “HarmonyTalk” took place at the Ersbārān Cultural Center. The event garnered such interest from enthusiasts that the venue was completely filled.

Finding a way to harmonize the Iranian music has been the subject of controversy among Iranian musicians for a long time. Some believe in the creation of harmonies for Iranian music based on a method which is similar to the tierce harmony; while others have either selected or invented some other methods. There are also some musicians who do not basically agree with the harmonization of the Iranian music.

In heterophonic variant, two performers perform a single melody simultaneously and change it. Performing and changing a single melody simultaneously by two performers leads to the coincidence of different voices.

Ali Tajvidi (1920 – 2004), one of the most prominent Iranian musicians, passed away sixteen years ago. He was one of the most distinguished Iranian artists. To specify one of the fields in which he was unique, one can refer to Tasnif composition. A brief review of his manifold musical activities is presented below.

One of his works was the translation of Harmony, which was carried out with the help of Mozayyan al-Dowleh, and included a pamphlet based on which he used to teach the subject to the students of the school of music; the pamphlet was never published. It was, in fact, a kind of simple harmony for the piano with no quadriads, it rather featured the engagement of both the right hand and the left hand which was being taught at the music school for the first time. Salar-Mo’azez also composed military marches and hymns for schools, which he harmonized to be performed and piano. Likewise, he used to compose for military orchestras.

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.

Fantasia on One Note was my first professional work for piano, which had its world premiere by the great pianist Peter Jablonski in Sweden, and it has been performed by various pianists in the UK, Germany, France, and the Czech Republic. The recording of this work has also been broadcast on the Dutch public radio, NPR Radio 4.

Gholamreza Khan Minbashian taught courses such as organology, orchestration of military music and harmony based on the books which were translated from French into Persian with the help of Aliakbar Mozayyan-o-Dolleh (1846-1932).
