To achieve this, the assessment and valuation of music performances by the professors and professionals can be noted as the most important academic means in order to distinguish between accurate and inaccurate performance in line with providing patterns and training the players. However, is it possible to assess music in a quantitative manner followed by marking its performance? If positive, based on which criteria and standard? Composing music and translating it into text, or in general, scores and revising and performing it depend on factors which are less adaptable to the current scientific-academic approaches of the date.
