To get an excellent English mark, you really do need to be ideas and values-focused in your essays. In my opinion, the subject is supposed to be focused upon general aspects of human nature that will be eternally relevant (belonging, conflicting perspectives), and then the use of a wide range of texts is merely to support those ideas, or provide proof. If you or your teacher view English as being all about the analysis of a text, then either or both of you are focusing too narrowly on the subject. Just because you have a shit tennis coach, or you hate tennis, or the specific rules of a certain competition don't appeal to you, or you take no pleasure in sport whether for leisure or for health reasons, does that mean the entire notion of tennis is stupid?
Yes, a composer may not say to herself, "I am employing the use of emotive language here to evoke sympathy from the audience" - that is absolutely ridiculous. However, she is probably feeling overwhelmed, wanting sympathy, and subconsciously inclined to speak in such a way that others will pity her. Of course, no writer would consider, "Should I use morbid imagery here to convey ideas of death and mortality, or barbaric connotations to provoke disgust?". Instead, it will probably come naturally to him, just like it is natural for you to:
Sitting here in english and im about to shoot myself in the head. English is without doubt the biggest fuckery to have ever been created straight out of Satan's arsehole.
employ the use of crude, vulgar language in order to convey your strong disgust of the subject.
That is exactly the same as being like:
A: "I fucking hate this shit excuse for a subject." - (Composer)
B: 'Hey C, why is A swearing so much?' - (Essay question/marker)
C: 'He mad.' - (Your interpretation, response/answer to the question)
- except that you're attempting to convey it appropriately in an essay format, just like how you can't just say 'The answer is 35cm because it just fucking is' in a maths test, and instead need to convey it appropriately with logical reasoning and working out.
In English, the markers want us to do several things - understand common themes and values and develop complexity of ideas, convey this understanding appropriately and effectively, and develop personal expression and fluidity of language. Yeah, you can get away with a half-decent mark without actually doing any of these things properly, but you can get away with a half-decent mark in any subject even if you don't learn everything properly.
