Frederic Anthony Rzewski (April, 13, 1938-) is a living, breathing American composer, well known for actively expressing his political ideas through his compositions; many of his works are inspired by socio-historical themes, one of which is "The People United Will Never Be Defeated!. Premiered in 1975, this piece consists of 36 variations on the song, El pueblo unido jamas sera vencido by the Chilean composer, Sergio Ortega. It is referred by many as a "political narrative masterpiece of the classical music in the twentieth century" because of the effectiveness with which, through musical structure and ideas, it conveys the intended message. In conceptualizing this piece, Rzewski chose a structure similar to the Goldberg Variation by Johann Sebastian Bach, which consisting of an aria and a set of 30 variations, because(.............); he divided the variations into six sets of six, each of which symbolizes a different political sentiment: people`s unity, struggle, clear political message are expressed through a meticulously calculated order. Each of the six sets of variations differ amongst one another in simple structure, rhythm, melody, counterpoint ad harmony. As shown in this paper, Rzewski harmonized his strong political and musical ideas with traditional elements of romantic lyricism.
