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.

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.

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.

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.

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.

Regional music festivals are organized to, firstly, introduce the music of different regions and, secondly, to support its performers. Regional music festivals are held in large cities for various reasons, including the availability of financial and executive facilities and the presence of an audience. However, the organization of these festivals has always been one of the challenging issues of ethnomusicology. The reason is that the presence of regional music performers in large cities places them in a context other than the context they would normally perform in their homes; consequently this change in situation leads to changes in the quality of their performance.

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.
