This is a contrapuntal work from Frescobaldi's 'Il secondo libro di toccate', showcasing the mastery of fugal writing in the early 17th century. It is distinguished by its intricate subject development and rigorous imitative texture.
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 precise articulation — the difference between crisp and blurred is the piece.
Beyond that, expect ornaments that need to sound effortless, not squeezed in.
The performer must maintain absolute clarity in the independent voices while executing idiomatic Baroque ornamentation.
