Louis Hector Berlioz (1803–1869) was a master of the large-scale orchestral form, known for his innovative use of instrumental color and dramatic narrative. While his primary output was symphonic, his influence on piano literature comes through his revolutionary approach to texture and drama. Transcriptions of his works, such as the "Symphonie fantastique," demand an orchestral approach to the keyboard, requiring the pianist to evoke various instrumental timbres and maintain a clear narrative line. His music challenges performers to think beyond the keys and imagine the vast sonorities of a full romantic orchestra.
