Carl Friedrich Zelter (1758–1832) was a significant German composer, conductor, and music educator, primarily known for his contributions to classical music and choral works. He was associated with the late Classical and early Romantic periods. Zelter was particularly noted for his choral compositions and his advocacy for the performance of Johann Sebastian Bach’s works, helping to revive interest in Bach during a time when his music was largely neglected. One of Zelter's notable works is the "Lieder" (songs) for voice and piano, which showcase his melodic inventiveness and lyrical style. He also composed "Die Geisterinsel," an opera that reflects the Romantic aesthetic. His arrangements of folk songs and his contributions to educational music, especially through his role as a teacher and the founder of the Berlin Singakademie, had a lasting impact on music education. Zelter's influence extended to his mentorship of composer Felix Mendelssohn, who furthered the appreciation of Bach and nurtured the development of choral music. Overall, Zelter's legacy lies in his role as a bridge between the Classical and Romantic eras, his dedication to choral music, and his efforts in music education.
