Polyphonic music is a style of music that features multiple independent melodies played or sung simultaneously. This technique allows different musical lines to interact with each other, creating a rich and complex sound. It is commonly found in various 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 used intricate counterpoint to weave together different melodies. In polyphony, each voice or instrument maintains its own distinct line, contributing to the overall harmony and texture of the piece.
