This is a contemporary neo-baroque set of variations on a ground bass. It is distinctive for its fusion of traditional passacaglia structure with modern harmonic sensibilities.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: independent voices that must each sing on their own line; precise articulation — the difference between crisp and blurred is the piece; and chord voicing — bringing out one note inside a handful of others.
Beyond that, expect ornaments that need to sound effortless, not squeezed in.
The primary challenge lies in maintaining a steady pulse while articulating the repetitive bass line.
