How does Schumann's approach to lieder differ form Schubert's?

Schumann's approach to lieder often emphasizes psychological depth and emotional complexity, integrating the poet's text with intricate musical interplay that reflects the characters' inner experiences. In contrast, Schubert's lieder are characterized by their lyrical beauty and melodic flow, focusing on the clarity of the text and the immediate emotional impact. While Schubert's songs often feature straightforward forms and rich melodies, Schumann experiments with varied structures and harmonic innovations, creating a more dramatic and narrative-driven experience. Additionally, Schumann frequently incorporates elements of narrative and theatricality, reflecting his background in literature and his interest in character development.
