being heard, reminds the hearers of the doom pronounced on the possessors of the ring by Alberich.
A yet more pregnant instance is in the Gotter- dammerung, the last of the series. When Sieg- fried comes to the Hall of the Gibichungs on the Rhine, with the ring in his possession, having obtained it by slaying Fafner, who had taken the form of a dragon to preserve it, the first per- son to greet him is Hagen, the son of Alberich, who looks to compass Siegfried's death, and re- gain the ring for the Niblungs by that means. As Hagen says 'Heil Siegfried, theurer Held,' the greeting is belied by the ominous sound of the leit-motif of the curse, which thus foretells the catastrophe in the sequel of which Hagen is the instrument and Siegfried the victim, and lends a deep and weird interest to the situation. Siegfried himself has ' motive ' assigned to him in different circumstances and relations. For in- stance, the following figure, which he blows on the silver horn made for him by Mime, is the one which most frequently announces his coming. It implies his youthful and light-hearted state before he had developed into the mature and experienced hero.
�� ��This figure is frequently subjected to consider- able development, and to one important trans- formation, which appears, for instance, in the death march as follows :
���In his character as mature hero he is notified by the following noble figure,
�� �� ��which occurs as above in the last act of the Walkiire, when Wotan has laid Briinnhilde to sleep on the ' Felsenhohe,' with a wall of fire around her; and the sounding of the motif implies that Siegfried is the hero who shall pass through the fire and waken Briinnhilde to be his bride. A happy instance of its recurrence is when, in the first act of Siegfried, the youthful hero tells how he had looked into the brook and saw his own image reflected there.
In the above examples the marked character of the figure lies chiefly in their melody. There are others which are marked chiefly by rhythm, as the persistent motif of Mime imitating the rhythmic succession of blows on an anvil
��which points to his occupation as a smith. This motif occurs in connection with the rattling blows of the hammers of the Niblung smiths underground, at the end of the second scene of the Rheingold, and thus shows its derivation.
Other 'motive' again are chiefly conspicuous by reason of impressive and original progressions of harmony. Of this kind that of the Tarnhelm is a good example. It occurs as follows, where Alberich first tests the power of the helm at the beginning of the third scene of the Eheingold :
���Another instance where a strongly marked melodic figure is conjoined with an equally strik- ing progression of harmony, is the 'death motif in Tristan and Isolde, which first appears in the second scene, where Isolde sings as follows :
�� ���A figure which it is difficult to characterise, but which has a marvellous fascination, is the motif of the love-potion in Tristan and Isolde.
���The love-potion is the key to the whole story, and therefore the musical portion of the work appropriately commences with its leit-motif. Among the numerous examples of its recurrence one is particularly interesting. When King Marke has discovered the passionate love which existed between Tristan and Isolde he is smitten with bitter sorrow that Tristan, whom he had so
