"The plastic unity and simplicity of the mythical subjects allowed of the concentration of the action on certain important and decisive points, and thus enabled me to rest on fewer scenes, with a perseverance sufficient to expound the motive to its ultimate dramatic consequences. The nature of the subject, therefore, could not induce me, in sketching my scenes, to consider in advance their adaptability to any particular musical form,--the kind of treatment being in each case necessitated by the scenes themselves. It could, therefore, not enter my mind to engraft on this, my musical form, growing as it did out of the nature of the scenes, the traditional forms of operatic music, which could not but have marred and interrupted its organic development. I therefore never thought of contemplating on principle, and as a deliberate reformer, the destruction of the aria, duet, and other operatic forms; but the dropping of those forms followed consistently from the nature of my subject." Nevertheless he could not proceed without any form, because music without form would be without design, and hence would not be an art. Form in music is based on the systematic repetition of fundamental melodic ideas. This constitutes the identity of the composition. A tune made of disjointed fragments, no two alike, is not a tune at all. A composition does not exist unless there is repetition of the melodic subjects of it. In the old aria form these repetitions existed within each aria, which formed in itself a separate composition. Wagner, having abandoned the aria form, was obliged to invent a new system of repetitions for his continuous melody. This he achieved by introducing the _leit motiv_, "leading motive" or "typical theme," a melodic phrase employed to designate a certain personality or thought in the drama, and heard, either in a voice part or in the orchestra, whenever that personality or thought is mentioned or has an immediate connection with the scene before the auditor. It was while composing "The Flying Dutchman" that Wagner invented his new system. In Senta's ballad, which tells the legend, he employed two themes. The first of these he intended to represent the Hollander, and to convey in some measure his unsatisfied longing for peace. [Music: THEME ONE--SOPRANO.] The second theme is intended to represent the complement to the former, the sacrificial love of Senta, which is to bring the peace. [Music: THEME TWO--SOPRANO, ALTO, TENOR, BASS.]
