Bortkiewicz was a master of the late-Romantic miniature, and these pieces reflect his highly melodic and melancholic style. His writing is characterized by lush harmonies and a deeply personal, narrative quality.
The challenge lies in shaping the long, arching phrases with enough rubato to sound natural without losing the pulse.
Comparable difficulty and character — good candidates for what to learn next.
