"Criterion of Iranian singing" Gholam Hossein Banan's position in the art world is such that it is not unreasonable to describe him as an irreplaceable figure in history of Iranian music; a name reminiscent of timeless sounds and pieces. Banan was a popular figure both among music experts and among the people, and had many fans and audiences. He was one of the first singers to become acquainted with and master the musical note. The constructive features of Banan's artistic importance are numerous and their description does not fit in this space, and his exemplary skill in correct recitation and perfect speech is just one of them. He was born on May 1, 1911 and died on March 29, 1985 in his hometown of Tehran. The importance of Banan in vocal music is that he is the only singer who is the bridge between the old tradition and the new approaches to singing in the modern era; That is, he is both the heir of a tradition that is associated with people such as Seyyed Hossein Taherzadeh, and the heir of the modern era of singing, which is related to Ali Naqi Vaziri and his students such as Ruhollah Khaleqi in a completely different style. Taking advantage of this difference, he has created brilliant works and no other singer has been as successful as him. In fact, if we examine the history of Iranian song in terms of the variety of styles and influences on the people through the media, we must divide it into before and after Banan. ~ Mir Alireza Mir Alinaghi
