All this, however, is the mere child's play of theme work.The more complex characters, instead of having a simple musical label attached to them, have their characteristic ideas and aspirations identified with special representative themes as they come into play in the drama; and the chief merit of the thematic structure of The Ring is the mastery with which the dramatic play of the ideas is reflected in the contrapuntal play of the themes.We do not find Wotan, like the dragon or the horse, or, for the matter of that, like the stage demon in Weber's Freischutz or Meyerbeer's Robert the Devil, with one fixed theme attached to him like a name plate to an umbrella, blaring unaltered from the orchestra whenever he steps on the stage.Sometimes we have the Valhalla theme used to express the greatness of the gods as an idea of Wotan's.Again, we have his spear, the symbol of his power, identified with another theme, on which Wagner finally exercises his favorite device by making it break and fail, cut through, as it were, by the tearing sound of the theme identified with the sword, when Siegfried shivers the spear with the stroke of Nothung.Yet another theme connected with Wotan is the Wanderer music which breaks with such a majestic reassurance on the nightmare terror of Mimmy when Wotan appears at the mouth of his cave in the scene of the three riddles.Thus not only are there several Wotan themes, but each varies in its inflexions and shades of tone color according to its dramatic circumstances.So, too, the merry ham tune of the young Siegfried changes its measure, loads itself with massive harmonies, and becomes an exordium of the most imposing splendor when it heralds his entry as full-fledged hero in the prologue to Night Falls On The Gods.
Even Mimmy has his two or three themes: the weird one already described; the little one in triple measure imitating the tap of his hammer, and fiercely mocked in the savage laugh of Alberic at his death; and finally the crooning tune in which he details all his motherly kindnesses to the little foundling Siegfried.
Besides this there are all manner of little musical blinkings and shamblings and whinings, the least hint of which from the orchestra at any moment instantly brings Mimmy to mind, whether he is on the stage at the time or not.
In truth, dramatic characterization in music cannot be carried very far by the use of representative themes.Mozart, the greatest of all masters of this art, never dreamt of employing them; and, extensively as they are used in The Ring, they do not enable Wagner to dispense with the Mozartian method.Apart from the themes, Siegfried and Mimmy are still as sharply distinguished from one another by the character of their music as Don Giovanni from Leporello, Wotan from Gutrune as Sarastro from Papagena.It is true that the themes attached to the characters have the same musical appropriateness as the rest of the music:
for example, neither the Valhalla nor the spear themes could, without the most ludicrous incongruity, be used for the forest bird or the unstable, delusive Loki; but for all that the musical characterization must be regarded as independent of the specific themes, since the entire elimination of the thematic system from the score would leave the characters as well distinguished musically as they are at present.
