Carl Borromaus Neuner (c. 1760 – 1833) was a German composer and music theorist known primarily for his contributions to the early Romantic music period. His work mainly encompassed the genres of sacred music, choral compositions, and orchestral music. Neuner's most notable works include his various mass settings, hymns, and cantatas, which reflect the transitional styles of his era, moving from the late Classical traditions towards more emotive Romantic expressions. Neuner was also recognized for his theoretical writings, which aimed to educate and guide musicians in the evolving landscape of music during the early 19th century. His influence extended through his teachings and compositions, as he worked to bridge the gap between the Classical and Romantic styles. Though not as widely known as contemporaries such as Beethoven or Schubert, Neuner's contributions to sacred music and his efforts in music education had a lasting impact on the development of choral and liturgical music in Germany. His works are appreciated for their melodic richness and harmonic innovation, paving the way for future composers in the evolving landscape of Western music.
