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.”

Music as an art has its own special history; emergence of a singer, of an instrumentalist and then the emergence of the strong character of a composer covers three significant phases of the art of music. With the emergence of composer which was simultaneous with the emergence of the language of music, this art managed to offer a domain for criticism for its composer; a procedure which led to a magnificent variety and evolution in musical production. Even though the conflicts between singers and instrumentalists have not met their end in the Iranian society and while singers can achieve high, instrumentalists have yet to play behind curtains . In a special era, with the efforts of musicians such as Ali Naghi Vaziri (1887-1979) and Rouhollah Khaleghi (1906-1965), glimmers of a composing era started to glow bearing fruit in Khaleghi’s achievement as Iran’s first professional composer. Khaleghi made his reputation as a composer while Vaziri deserved to pioneer this path. By then Vaziri was well-known as a Tar player.

The term “School of Vaziri” is often used in writings on Iranian music, but the exact meaning of the term is not clear; some of the authors have used the term to only refer to the group of Vaziri’s students, including a large group of his conservatory students and his Tar students such as Abolhassan Saba, Rouhollah Khaleghi, Ahmad Foroutan Rad, Hossein Sanjari, Heshmat Sanjari and others. But can we consider all Vaziri’s students as followers of his school of thought? This is definitely a mistake, because we know that some of Vaziri’s students have chosen a completely different path than that of Vaziri.

In an era when almost no trace of contemporary Iranian music can be heard in international concert halls, except (so-called!) avant-garde works that owe their existence solely to the fashionable slogans of the “pseudo-intellectual” crowd who have seized the already meager resources for performing classical music from the true artists of the field, the numerous performances of Farhad Poupel’s works shine as a ray of hope for lovers of sincere musical art. Without resorting to trendy slogans, he has kept the flame of Iranian classical music alive purely through the power of his artistry.

Joint application of the two techniques of “Lip” and “Nose” could be effectively applied for hearing and playing far-away intervals, by the Classical Guitar. Before this, a Classical Guitar player had to waive playing intervals not possible with the left hand, and had to replace or eliminate some notes, making it possible to play such intervals; specifically the capability of the left hand of the musician, was also a factor in such a selection. These methods are hereby illustrated by photographs and a video-file, in order to provide optimum comprehension of applying these methods, invented by the author; specifically the “Lip” technique, which is considered to be a more significant technique, emphasized by the author.
