The work opens with a wonderfully descriptive Prelude, which depicts with marvellous art (marvellous because so simple) the transition from the quietude of the water-depths to the wavy life of the Rhinedaughters. The double basses intone E-flat. Only this note is heard during four bars. Then three contra bassoons add a B-flat. The chord, thus formed, sounds until the 136th bar. With the sixteenth bar there flows over this seemingly immovable triad, as the current of a river flows over its immovable bed, the Motive of the Rhine.

A horn intones this motive. Then one horn after another takes it up until its wave-like tones are heard on the eight horns. On the flowing accompaniment of the 'cellos the motive is carried to the wood-wind. It rises higher and higher, the other strings successively joining in the accompaniment, which now flows on in gentle undulations until the motive is heard on the high notes of the wood-wind, while the violins have joined in the accompaniment. When the theme thus seems to have stirred the waters from their depth to their surface the curtain rises.

The scene shows the bed and flowing waters of the Rhine, the light of day reaching the depths only as a greenish twilight. The current flows on over rugged rocks and through dark chasms.

Woglinde is circling gracefully around the central ridge of rock. To an accompaniment as wavy as the waters through which she swims, she sings:

Weia! Waga! Woge, du Welle,
Walle zur Wiege! Wagala weia!
Wallala, Weiala weia!

They are sung to the Motive of the Rhinedaughters.
