"Hallelujah" is a word praising God in the Bible. Hallelujah, with this word as the main body of lyrics, is a genius masterpiece of Handel, a master of classical music, a representative figure of Baroque period and a great German musician. This is one of his masterpieces-the chorus in the oratorio Messiah. "Messiah" is a religious work, and its script is based on the sentences in the Bible, with chorus as the main body, and more than 50 songs in recitations, arias and other genres, which can be described as a long masterpiece. Handel wrote this work with great devotion and enthusiasm. In his writing, he is full of thoughts and ideas, and notes gush from his pen like a fountain. It took only 24 days to write this masterpiece, which became a story in the history of music. When he finished writing the chorus "Hallelujah", he was so excited that he burst into tears and said to the servant around him, "I really think I saw the whole kingdom of heaven in front of me, and I saw the great god himself!"
