Scope is appropriate neither too narrow or too broad. Such an article could be made appropriate in scope by reducing the biographical material to a paragraph or two that discussed aspects of the composer's life and works that were important to the present study. Works relevant to the thesis could then be selected for analysis. If the goal is to prove that this composer imitates the text-symbolism or rhythmic techniques of Bach, for example, a selective presentation of works that strengthen this point would be in order. If numerous works are studied as a part of preparation for the article, findings should be summarized rather than set out in detail work by work.
Information is precise, accurate, and well-documented.
Precise, objective descriptions are more effective at convincing readers that the work is wonderful, beautiful, or fine. This criterion covers a wide range of stylistic issues. For example, it is not known how many conductors the author has surveyed, if any, to support the first phrase above. Repeated use of passive voice also weakens an article's style. The goal is to encourage clear, interesting expository prose that is neither verbose nor chatty.
