<p>Music journalsim at its hight level is a valid literature gener, not a vicarious alternative to mastering an instrument.</p>
<p>The underlined part is gener, not a</p>
<p>I didnt understand why this sentence is correct.
i mean before a comma we need subordinate coordinate to be write?</p>
<p>Music journalism is a valid literature genre.
Music journalism is not a vicarious alternative to mastering an instrument.</p>
<p>Music journalism is a valid literature genre, not a vicarious alternative to mastering an instrument.</p>
<p>The part after the comma (“[is] not a . . .”) is adding on to the first part (“is a valid literature genre”). You don’t need a conjunction like and or but, especially when you have “not”: I am cold, not hot. I am standing, not sitting.</p>
