The twelve-tone system of composition was invented by Arnold Schoenberg. The twelve-tone technique is a term referring to a type of musical composition that came to replace the old basis of tonality and contribute a new musical structure. This technique involves the use of tone rows, ensuring that all twelve notes are heard without any emphasis on a specific note.
