Busoni's Duettino Concertante is based on Mozart's K. 459 piano concerto movement, transformed through his unique neoclassical lens. It features intricate contrapuntal dialogues and sophisticated harmonic coloring typical of his mature period.
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 chord voicing — bringing out one note inside a handful of others, and fast passage work that stays light and even at tempo.
At roughly 8 minutes, stamina and memory become part of the challenge — plan practice in sections.
The primary challenge lies in maintaining clear, independent articulation between the two contrapuntal voices while balancing the modern harmonic textures.
