My feelings are as follows:

"Ode to the Red Flag" adopts a sonata-style structure with a theme that develops throughout. The trumpet motive in the prelude of the song obviously comes from the "March of the Volunteers", taking the audience back to the exciting moment of the flag-raising ceremony at the founding ceremony on October 1, 1949;

The first part of the presentation part The theme can also be called the "red flag theme". This is a typical carol theme with ups and downs and a heroic spirit, as if it is the excitement and surge in people's hearts when they look up at the red flag rising; oboe and cello The second theme played successively is affectionate and euphemistic, and the cantabile melody nourishes the hearts of the listeners like gurgling water, and it also seems like the author is expressing his endless longing for his deceased relatives;

Although the expansion part comes from " "Red Flag Theme", but the rhythm has undergone a radical change, becoming a witty and courageous march. It seems that under the leadership of the red flag, the calm and resolute faces of the revolutionaries can be seen as they move forward bravely; although the recapitulation only appears "Red Flag Theme", but the addition of the national anthem motive not only keeps the music style unified, but also highly summarizes the carol theme of the entire work.

Extended information:

In 1965, in order to hold the "Shanghai Spring International Music Festival", Shanghai began to openly solicit performances. At that time, when the organizers were selecting the preliminary programs submitted by various units, they believed that the number of main theme works was not enough and the quality was not high. As a result, musicians such as He Luting, Ding Shande, Meng Bo, and Huang Yijun named Lu Qiming to hand over the creative task.

In order to compose the song, Lu Qiming spent a week thinking about it, trying to find an entry point to express the theme of "red flag". In the process of conception and creation, the father who was imprisoned and died heroically, the martyrs who generously died and fought for the next, and the five-star red flag rising at the founding ceremony of the People's Republic of China, all appeared in Lu Qiming's mind like movie scenes.

Finally, he completed the first draft of the song. During the creation process, Lu Qiming believed that the appreciation habits of the Chinese people should be respected, so he focused his creation on the performance of the melody.
