Simorgh (Simorq) Orchestra was founded by the renowned Iranian composer, Hamid Motebassem, in 2011. Simorgh Orchestra is the largest orchestra featuring Iranian national instruments. Although the orchestra established by Master Hossein Dehlavi, the great Iranian composer, in 1993 was larger than Simorgh Orchestra, it only featured the Iranian plucked string instruments unlike the latter one. The first album which was recorded by the Orchestra, conducted under Motebassem’s baton, was his Simorq based on Zal story from Shahnameh by Ferdowsi, the great Iranian poet.

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.

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).

In the few days prior to the New Iranian year (March 2015), the news of the revival of Tehran Symphony Orchestra under Ali (Alexander) Rahbari’s conductorship was announced. Ali Rahbari, who served as assistant to Herbert von Karajan in Berlin Philharmonic Orchestra at a very young age, was also invited to conduct Tehran Symphony Orchestra in 2005; however, the election of Mahmoud Ahmadinejad’s government put an end to his collaboration with this Orchestra. Recently, it was announced that Rahbari is invited to conduct an orchestra in the U.S.

Ali Tajvidi (1920 – 2004), one of the most prominent Iranian musicians, passed away sixteen years ago. He was one of the most distinguished Iranian artists. To specify one of the fields in which he was unique, one can refer to Tasnif composition. A brief review of his manifold musical activities is presented below.

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

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.

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.

The collaboration between Mozart and Haydn blossomed during the late 18th century in Vienna, a city that served as the epicenter of musical innovation. Amidst this vibrant cultural milieu, the two composers developed a profound friendship that extended beyond mere professional admiration. This connection is reflected in the six string quartets dedicated by Mozart to Haydn, aptly known as the “Haydn Quartets.”

Despite the fact that Iranian folk music (regional music of Iran), like the Radif of Iranian traditional music, is monophonic and follows heterophony in principal, we experience polyphonic forms, albeit, majorly unconscious.
