If I were a bird is an ancient German folk song. The lyrics borrow a bird's tone to educate students to form a good habit of cherishing time, studying hard and working hard in their youth. "Young people will be sad if they don't work hard." The theme of the song is clear and concentrated, the music language is concise and the structure is complete. With the gradual addition of three choruses, simple harmony is rich and full, which enhances the three-dimensional sense, image and interest of music and gives people beautiful enjoyment.
