Ludwig van Beethoven's early training profoundly influenced his later compositions. His first music teacher was his father, who was a harsh instructor, enforcing discipline in Beethoven's studies. This rigorous early instruction laid the foundation for his technical skills and musical knowledge. Beethoven also studied with Joseph Haydn, absorbing classical styles that he later transformed. His exposure to the musical traditions of Vienna, combined with his innovative spirit, allowed him to push the boundaries of composition. The struggles he faced with deafness further shaped his work, leading to a unique sound that defined the transition from the Classical to the Romantic era.
