Berg-Idylle is a highly evocative, programmatic work that attempts to capture the stillness and grandeur of mountain landscapes. It is notable for its rich, pianistic textures and lush harmonic language.
The primary challenge is layering the complex, thick chords while keeping the melodic line expressive and singing.
