This is a variant entry for the same Shcherbachov composition as piece 3 and 4. The work exhibits a characteristic Russian melancholic tone with chromatic inflections.
The performer must carefully balance the dense, overlapping chordal textures to ensure the melodic line emerges clearly.
Comparable difficulty and character — good candidates for what to learn next.
