This Rondo in the third movement of Beethoven's "Dawn Sonata" has a huge length and a very distinctive singing tone. It is brightly colored, like a bright morning. Compared with the first chapter, it seems to "enter the vast sky". Its voice is loud, clear, transparent and textured, and everything seems so simple and natural. He is a brilliant example of Rondo processing, a typical Rondo style, which adopts the principle of ABACA well, and at the same time expands each part into the form of ABACAB, and the speed is gradually accelerated with the advancement of music. The result was even more gorgeous and set off a gripping climax. Beethoven's book attempts to expand this Rondo into more magnificent commemorative music, and create its own unique melody on the basis of studying and feeling the tones of folk songs in many aspects. The main performance factors of the whole area are: happy running, whirling, whispering from the heart, rustling of leaves and singing of birds, which embodies the infinite happiness in the embrace of nature and the infinite miracle of God-Lord Jesus Christ. And clearly shows the romantic landscape style symphony. The beautiful and cheerful theme is a phrase expanded into a long breath, which is the singing of grapes in the Rhine region. It gives people a fresh feeling, just like the breeze on the Rhine River, full of happiness and clear and simple beauty, which brings people into the joyful atmosphere of folk festivals. The soft singing is louder and louder, and the mood is more and more joyful, which expresses people's love for life and praise for their hometown, the joy of workers and their happiness. A series of powerful triplets lead to the first insertion of B, which is vigorous and resolute in nature. The {Tarantella Dance} in A minor is first played by the left hand with octaves in the bass area, and the right hand actively decomposes the octaves to echo it, depicting a scene in which young men dance rough and powerful, and girls are at the side. The melody of the dance music gradually turns to the right hand, and fast-rotating patterns are inserted from time to time. As if the second complete reappearance, beautiful and moving folk songs and warm martial arts scenes appeared alternately, making the musical artistic conception ups and downs and colorful. The second plug-in C depicts another dance scene with the bold melody of alternating left and right hands, which is loud, fast and intense music. When the main theme appeared for the third time, the lyric mood was stronger than before, and it gradually rose with the energetic triplet. The intensity is getting stronger and stronger, and the jubilant atmosphere has reached a climax. The end of the whole song is a huge, relaxed and happy dance music, a broad victory song, which is essentially a large and colorful part of the piano concerto. The whole song is based on the basic material of the main theme, and finally the whole song ends in an extremely warm martial arts scene. In a word, this movement is an ode to the vibrant nature of mankind. Roman and Roland's evaluation of this piece of music is "vast and boundless plain, full of sunshine." . . . . It seems like summer, and such days are never enough! . . . . . . However, the composer did not use counterpoint and harmony. According to nagel's fair view, whenever Beethoven wanted to express himself full of strength or high happiness, he got rid of any fancy about himself, and his music language was particularly simple in harmony.
