Sima Bina (b. 1945) is a unique singer among the singers of Golha radio programmes which were broadcast on Iranian National Radio for 23 years from 1956 to 1979. She received her first lessons in music from her father who was a poet, a musician and the most important supporter of Sima’s cultural activities.

Gholam Reza Khan Minbashian, a.k.a Salar-Mo’azez, was a pioneer in several domains in the history of the Iranian music. He is recognized as the first Iranian musician who was educated in classical music. He is also the first Iranian the score of whose works were published in Europe. He is the first Iranian to have launched courses on Western classical music and was also the first Iranian teacher of classical music. Moreover, he is the first founder of a string orchestra in Iran, the first author of the Iranian Radif which was available in oral form. Minbashian is also the first Iranian who studied music in Europe.

Ashura Opera was composed by Behzad Abdi, the Iranian composer, in 2008 based on librettos compiled by Behrouz Gharib. The main source for the libretto is poems by Mohtasham Kashani, a sixteenth century Iranian poet.

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.

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.

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.

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

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.

Two choirs alternatively perform Veŝ Tavaré Na avaz (Transcription 5). The second group starts the avaz before the first group finishes it; consequently, two different voices coincide (Transcription 5, staves 2 and 5).
