The music of "Das Rheingold" is beautifully written to fit every person and every situation. The famous opening starts with a low chord of E flat which describes the bottom of the river Rhine. At first the notes of the chords are held on, then gradually a ripple of broken chords and arpeggios suggest the ripples of the water. The harps make a sound like the waves. The harmony just consists of the same E flat chord for the first 136 bars until the Rhine Maidens start to sing.
