The loudness of tone in Jane Eyre is undoubtedly effective…

““The loudness of tone in Jane Eyre is undoubtedly effective in communicating tension and frustration, but the style does of course have its related limitations. It precludes the use of the small suggestive detail or the quiet but telling observation that Mrs Gaskell and George Eliot are so good at. In such a fortissimo performance as this, the pianissimo gets drowned out, or noted only as an incongruity (which helps to account for the book's moments of unintended comic bathos). Again, it makes the whole question of modulation of tone a difficult one,6 and it is also hard to manage irony elegantly, as the Brocklehurst and Ingram portraits show. There is unconscious ambiguity but little deliberate irony in Jane Eyre. Hence the remarkable unity of critical interpretation of the book—the reader knows all too well what he is meant to think about the heroine and the subsidiary characters. The novel does not merely request our judicious sympathy for the heroine, it demands that we see with her eyes, think in her terms, and hate her enemies, not just intermittently (as in David Copperfield) but in toto. It was, incidentally, because James Joyce recognised the similar tendency of Stephen Hero that he reshaped his autobiographical material as A Portrait of the Artist as a Young Man, retaining the 'first-person effect' but building in stylistic and structural irony that would guard against the appearance of wholesale authorial endorsement of Stephen.””
