The world of music has unparalleled respect for Bach. Bach is considered the spiritual father of classical music; Bach’s great position is due not only to his great achievements in the fields of harmony, counterpoint, and compositional sciences but also to his respect for and adherence to the artistic principles of classical music. In the history of classical music, it is recorded that Bach walked about fifty kilometers to listen to the music played by the great German organist Dieterich Buxtehude, and this is the path that every idealistic classical music student should walk.

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

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.

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.

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).

Discussions and research have been conducted on the harmonization of “dastgah” and melodies in Iranian music, and several books have been published on this topic, including “Armenian Music of Iran” by Ali Naghi Vaziri, “Harmony of Iranian Music” by Farhad Fakhreddini, and “Harmony of Iranian Music” by Ali Ghamssari. A master’s thesis titled “Presenting a Solution for Harmonizing Based on the Structure of Tritone Intervals” was written by Atefeh EinAli in 2014. Additionally, the invention and use of “Even Harmony” by Morteza Hannaneh should be mentioned.

Music education in third-world countries is facing many problems that limit access to it and it’s full of challenges. These rising and falling obstacles are made of the socioeconomic, cultural educational systems, etc.

Joint application of the two techniques of “Lip” and “Nose” could be effectively applied for hearing and playing far-away intervals, by the Classical Guitar. Before this, a Classical Guitar player had to waive playing intervals not possible with the left hand, and had to replace or eliminate some notes, making it possible to play such intervals; specifically the capability of the left hand of the musician, was also a factor in such a selection. These methods are hereby illustrated by photographs and a video-file, in order to provide optimum comprehension of applying these methods, invented by the author; specifically the “Lip” technique, which is considered to be a more significant technique, emphasized by the author.

Rouhollah Khaleghi was the master of composing beautiful melodies. He was the premier of the course of history which was first established by Ali Naghi Vaziri and which improved the Iranian music from simply a gathering music to the classical music of the country. First efforts to compose independent and instrumental music can be also traced in Khaleghi’s works.
