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.

Tajvidi thought of studying harmony and orchestration with Houshang Ostvar (who was eight years younger than him) at a time when he had gained a reputation among musicians. His humbleness, making him willing to kneel before the scholars at any age and position, became the key to his scientific success. After this period, Tajvidi made some of his works polyphonic, the most prominent of which is “Burn” set to a poem by Abdullah Ulfat. However, his ability to make his works polyphonic was not so great to make him self-sufficient; so he depended on musicians such as Farhad Fakhreddini, Fereydoun Naseri, Kambiz Roshanravan, Fereydoun Shahbazian and Morteza Hananeh for the arrangement of his compositions.

With Dehlavi it is not all about fame but recognition. Hossein Dehlavi is not a popular musician (like pop singers) whom everybody might know when he is walking on streets of Tehran; however, he is recognized by both amateur and distinguished musicians of the country.

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).

The name of Maestro Hassan Kassai is so vehemently intertwined with Ney (Persian reed flute) that one cannot imagine one without the other immediately coming into mind. Ney is one of the instruments which went through a lot of ups and downs in the history of the Iranian music since the time of Sassanid kings to the time when shepherds found playing it consoling when they took their cattle for grazing. However, Nay could never demonstrate its main capacities to gain a stable position among the musicians and the people like other instruments including Oud, Tar, Santour, all sorts of bowed string instruments and plucked string instruments.

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

When the author was working on the piece “Playing Love” by Ennio Morricone (from the legend of 1900), he realized a failure of the Lip Technique. Needing to play a chord in the 14th position of the guitar and in order to complete the harmony, it is necessary to play a harmonic note on the 7th or 5th position; it was not possible to touch the string to play this harmonic note, because the Lip Technique is used for getting the notes and not to touch the string and producing harmonic notes. Naturally, the only possible way to touch the string was to use the nose at the required position and playing the note with the right hand, and this was the best option the author found to how to play such harmonic notes, and where the Nose Technique was generated.

In Iranian music, certain singers have become emblematic of their homelands through their distinctive voices. Historical figures such as Eghbal Sultan, who epitomized the grandeur of Azerbaijani music, and Taj Isfahani, who conveyed the authentic essence of Isfahan, serve as notable examples from the Qajar era. Nasser Masoudi occupies a similar position; his voice emerged as a symbol of Gilan while also achieving national acclaim. Before him, Master Ahmad Ashurpur represented Gilan’s musical landscape, but his extended residence outside Iran limited his continuous engagement in the music scene. In contrast, Masoudi’s consistent presence allowed him to introduce the voice of Gilan to audiences across Iran.
