Ali-Naqi Vaziri, a respected player of numerous persian and western instruments who studied western musical theory and composition in Europe, was one of the most prominent and influential musicians of the late Qajar and early Pahlavi periods. He established a private music school in 1924, where he also created a school orchestra composed of his students, formed by a combination of the tar and some western instruments. Vaziri then founded an association named Music Club (Kolub-e Musiqi), formed by a number of progressive-minded writers and scholars, where the school orchestra performed concerts that were conducted by himself.
