Sing a folk song for the party and listen to the difference between the three melodies.

Singing a folk song to the party is different in lyric and rhythm.

1, lyrical, the first paragraph has obvious lyricism, the theme is based on the clear A Palace mode, the tone is bright and round, and the feelings are sincere, expressing the infinite love for the party. In the second paragraph, from the A Palace mode to the F Feather mode, the gloomy tone, such as weeping and indignation, shows the hatred of the old society and the strong contrast between the old and the new. The third paragraph reproduces the theme of the first paragraph. At this time, the singing tone will be clearer and more stretched than the first paragraph, thus showing higher and more exciting emotions and pushing the music to a climax. The change and contrast of the timbre of the whole song perfectly expresses the theme and emotion of the song.

2. In terms of rhythm, the harmony of a paragraph is relatively simple, and the accompaniment texture combines polyphony, chord and melody. The rapid vibrato in the first half of the second paragraph shows the darkness of the old society and is eager to rush to the light. The accompaniment texture in the second half turned into lively and brisk chords, which made people feel suddenly enlightened and showed the excitement of following the * * * proletarian revolution. Between the first paragraph and the second paragraph, the three rhythms go down in a roundabout way, which makes full preparations for the song to transition from cheerful mood to sad and depressed mood.
