This arrangement of Marcello's Oboe Concerto in D minor shows Bach's expressive ornamentation in minor keys. Its expressive slow movement and driving outer movements display profound harmonic depth.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: independent voices that must each sing on their own line; ornaments that need to sound effortless, not squeezed in; and a true singing tone, with the melody floating above the accompaniment.
Beyond that, expect fine finger independence within the hand, and precise articulation — the difference between crisp and blurred is the piece.
At roughly 9 minutes, stamina and memory become part of the challenge — plan practice in sections.
Ensure the cantabile line in the slow movement is sustained through expressive, nuanced phrasing.
