How did Hector Berlioz influence Franz Liszt’s music?

The French composer Hector Berlioz exerted a significant influence on the musical development of Franz Liszt after the two met in 1830.1

Liszt’s artistic growth was shaped by Berlioz in several key ways:

• Orchestration: Liszt gained a mastery of enlarged orchestral forces through his study of Berlioz’s work.21
• Thematic Technique: Liszt adopted the concept of thematic transformation—as opposed to traditional development—which was an extension of Berlioz’s idée fixe used in works like the Symphonie fantastique.21
• Stylistic Elements: Liszt inherited a certain diabolic quality from Berlioz that persisted throughout his career.1

Liszt demonstrated his admiration for Berlioz by transcribing the Symphonie fantastique and other works for the piano, helping to promote Berlioz's music in concert. Additionally, Liszt dedicated his Faust Symphony to Berlioz, a work that exemplifies his application of these influences through its balanced structure and thematic parody.12
