Johann Sebastian Bach did not compose opera, as this genre was not a focal point of his work. While he wrote significant instrumental and vocal music, including cantatas, concertos, and oratorios, the operatic form was more developed by his contemporaries like Handel. Additionally, he did not create popular music or folk music, which were outside the scope of his compositional style and training.
