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.

The present series of training articles, “Principles of Violin Playing”, seek to help students, to appropriately understand this field, by gradually introducing, categorizing, and teaching the myriad relevant points. One of the principles of playing violin, which must be always kept in mind, is that the selection of the most natural position for the body parts while playing is the best and most appropriate solution. As a matter of fact, any unnatural body part position which requires lots of energy or unusual stretching to maintain, is wrong.

With this description, we have automatically included a criterion called “History”, Until we know the time of the creation of a work of art, we cannot judge whether it has been easy to create or not. Suppose that, in a historical study, we find a musical work that is similar in compositional techniques (including form, melody, context, and orchestration) to a minor work of the nineteenth century; however, our research proves that, this work dates back to 200 years prior to that date. Can we still consider this work insignificant? Definitely not! So this is where the first use of history-based judgment comes into play.
