The work is scored for solo oboe and an orchestra consisting of two flutes, two oboes, two clarinets, two bassoons, two French horns, and strings. It is in one movement with three distinct sections:[2]
- I. Risoluto allegro
- II. Larghetto cantabile
- III. Allegro polonese
The piece is a concerto "all'italiana", a relatively new form in Bellini's time, which consists of an introduction, a slow section, and an Allegro.[2] The first section, marked Risoluto allegro, is only nine bars long and in the key of G major. It does not develop any melodic material in the rest of the piece, and it consists of a chord progression that makes heavy use of chromatic intervals.[2] Naxos Records referred to it as "the shortest of dramatic introductions".[1] Charles-David Lehrer opined that the concerto "deleted the first movement structure", in contrast to previous concerti for the oboe.[7]

Lehrer also stated that most pieces without an extensive first movement were labeled as concertinos.[9]
The second section, Larghetto Cantabile, marks the first entrance of the oboe and transitions to E-flat major, a major third down from the previous key of G major. In this section, the oboe soloist has several short cadenzas, expressive melodies, and fermata notes. The section can be divided into three subsections.[2] Hyperion Records called the oboe part in the section "aria-like", stating that it was typical of the bel canto style that was to influence Frédéric Chopin.[3]
The third and final section, a polonaise marked Allegro, is the largest section of the piece and changes the time signature to 3/4.[2] The section shows a greater amount of interaction between the solo and orchestral parts, as there is frequent imitation and trading off of the main theme.[2] One compiler and publisher of Bellini's music called the section a rondo in the structure "ABACABX"; he also wrote that "the orchestra connects the different episodes by short riffs […] and replies once the main theme."[10] Lehrer noted this third section as part of the common trend towards polonaises in rondo format as final movements of Romantic oboe concerti, listing it with works by Carl Maria von Weber, Stanislas Verroust, and Georges Guilhaud.[9]
