Fétis believed that tonality, tonalité moderne , was entirely cultural, saying, "For the elements of music, nature provides nothing but a multitude of tones differing in pitch, duration, and intensity by the greater or least degree ... The conception of the relationships that exist among them is awakened in the intellect, and, by the action of sensitivity on the one hand, and will on the other, the mind coordinates the tones into different series, each of which corresponds to a particular class of emotions, sentiments, and ideas. Hence these series become various types of tonalities."( Fétis 1844 , 11–12) "But one will say, 'What is the principle behind these scales, and what, if not acoustic phenomena and the laws of mathematics, has set the order of their tones?' I respond that this principle is purely metaphysical [anthropological]. We conceive this order and the melodic and harmonic phenomena that spring from it out of our conformation and education."( Fétis 1844 , 249)
While taking one side of an issue over another is clearly based on your opinion, you can make objective writing a reality by avoiding first-person and second-person pronouns. The fact that the paper is yours makes it clear that the ideas, thoughts and conclusions that are not cited are your own. Unless you are conducting primary research and discussing it, write in the third person using third-person pronouns when applicable. Otherwise, personal comments, such as “I think” or “my opinion is” come across more as a biased opinion rather than a logical argument with supporting evidence.
Briefly state your position, state why the problem you are working on is important, and indicate the important questions that need to be answered; this is your "Introduction." Push quickly through this draft--don't worry about spelling, don't search for exactly the right word, don't hassle yourself with grammar, don't worry overmuch about sequence--that's why this is called a "rough draft." Deal with these during your revisions. The point of a rough draft is to get your ideas on paper. Once they are there, you can deal with the superficial (though very important) problems.
