For use in military bands, western musical instruments were imported and taught. These woodwind and brass instruments were essentially incapable of producing intervals peculiar to native music. Later, other instruments were brought into the country. The violin, in particular, found great favour among the local musicians as it could fully express the intervals and nuances of Persian music. Quite to the contrary is the case of the piano, also introduced in the late nineteenth century, as it is undoubtedly the most unsuitable of instruments for Persian music.Finally, the school of music introduced into Persia the idea of a methodical and pedagogically organised approach to the study of music. In the traditional way, the study of music was confined to the study of an instrument according to the personal methods of a teacher; any knowledge of the music itself was only incidental to the practical training. Western procedure introduced the idea of the uniformity of systematic study integrating the technique of performance with theoretical learning, all of which was written and taught with uniformity and precision (Source: The Dastgah Concept in Persian Music).
