Polyphonic music is a style of music that features multiple independent melodies played or sung simultaneously. This technique allows for a rich and complex sound, as each melody interacts with the others, creating harmony and texture. Polyphony is often found in various musical genres, including classical, folk, and even some forms of popular music. One of the most notable examples of polyphonic music is the works of Johann Sebastian Bach, who skillfully combined different melodic lines in his compositions. In addition to classical music, polyphony can also be observed in Gregorian chant and Renaissance choral music, showcasing its historical significance and versatility.
