One of the most important criteria for measuring the quality of a piece of classical music is number of times the piece has been performance by different ensembles and orchestras in different eras. This belief has become so pervasive in some societies, such as Iranian society, that it is considered the only criterion for measuring the quality of a piece of classical music.

4.3.1. To practice playing of doubles of notes involving two different fingers, each note is played at separate bows with slow tempo, each note is played perfectly regarding its bass and tenor sounds and then the considered double is played at another bow while considering the resulted sound of the double.

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.

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.

A part of the secrets of the masterpieces from the golden era lies in the special design of the instruments, as a result of a profound insight to and awareness of the significance of the precise calculation of the various components of the object of arts being created, such as making a violin or a bow.

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.

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.

In response, it should be said that it is better for the national anthem of a country to use the musical material exclusive to that country; however, some problems might come up in doing so the most important of which include: lack of familiarity of other countries’ music performer with the concerned country’s specific music intervals and special musical technique; and secondly, the strangeness of that music to the foreign listener.
