At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: independent voices that must each sing on their own line; fine finger independence within the hand; and ornaments that need to sound effortless, not squeezed in.

The main technical challenge is executing clear, distinct articulations for the independent voices throughout the complex counterpoint.
