The Area of Study 1 set work for first assessment 2026, Beethoven Symphony No. 1 in C major Op. 21 first movement (Adagio molto - Allegro con brio), its slow introduction, sonata form, harmony, tonality, texture, orchestration and Classical context, as examined in Section B of the listening paper.

What this dot point is asking

For first teaching 2024 and first assessment 2026, AQA prescribes one set work (study piece) for Area of Study 1: the first movement of Beethoven's Symphony No. 1 in C major, Op. 21 (marked Adagio molto - Allegro con brio). It replaces the Mozart Clarinet Concerto, whose final assessment was 2025. You study this movement in depth because it is examined in Section B of Component 1 (the listening paper), where set-work questions carry 28 of the paper's 96 marks. You need to know its structure, melody, harmony, tonality, texture, orchestration and Classical context well enough to answer detailed and extended questions on it, and to apply the same knowledge to unfamiliar Classical extracts in Section A.

Context: why this work, and where it sits

Beethoven wrote Symphony No. 1 around 1800, at the very end of the Classical period and the start of his own career. It sits in the Classical tradition: it follows the model of Haydn and Mozart in its forces, forms and balance, so much of what you already know about the Classical period applies directly. At the same time, Beethoven pushes at the conventions, with a deliberately unsettled opening, strong sforzando accents, sudden dynamic contrasts and rhythmic drive that hint at the more dramatic Romantic style to come. In the exam, linking the work both to its Classical models and to Beethoven's individual energy is exactly the contextual point AQA rewards.

The slow introduction (Adagio molto)

The movement does not begin with the main fast music. It opens with a short, slow introduction marked Adagio molto. Its most famous feature is that it begins off the tonic: the very first chord is a dominant seventh that resolves not to the home key of C major but onto a chord that points toward F. This deliberately obscures the key, so the listener cannot be sure they are in C major until the fast section arrives.

The introduction is homophonic and quiet (piano), with the strings and wind moving in chords, chromatic harmony, suspensions and expressive crescendos that build a sense of anticipation. Its job is to create tension and uncertainty that the Allegro con brio then resolves by firmly establishing C major. Recognising this unusual, unsettled opening is one of the quickest ways to identify the set work in the exam.

The fast section: sonata form

Sonata form is built on tonal contrast and return. In the exposition the music moves away from home, from C major to the dominant G major, to set up the contrast between the two subjects. The development then explores the material in a range of keys, raising tension, before the recapitulation resolves everything by bringing the second subject back into the tonic rather than the dominant. The coda reinforces C major one last time. Tracking these key relationships is the most reliable way to follow the structure by ear.

Melody, harmony and tonality

The melodies are tuneful and largely diatonic, built from scales, arpeggios and short motifs that Beethoven repeats, sequences and develops. The first subject is energetic and rhythmic; the second subject, in the dominant, is more lyrical, giving the contrast sonata form needs.

The harmony is functional and mostly diatonic, using primary triads (I, IV, V) and the dominant seventh, with perfect and imperfect cadences punctuating the phrases and occasional chromatic chords and pedal notes for colour and tension. The tonality is centred on C major: the exposition modulates to G major (the dominant), the development ranges more widely through related keys, and the recapitulation returns home. The off-key introduction is the one place where the tonality is deliberately unclear.

Texture, orchestration and dynamics

The texture is mostly homophonic (a clear melody over chordal accompaniment), but Beethoven varies it with imitation between sections, antiphonal exchanges (call and response between strings and wind) and fuller tutti passages. The work is scored for a Classical orchestra: paired flutes, oboes, clarinets and bassoons, horns and trumpets, timpani, and strings. There is no harpsichord continuo, which had been abandoned by this date.

Try this

Q1. In which key is Beethoven's Symphony No. 1, and what is unusual about how the first movement begins? [2 marks]

• Cue. It is in C major, but the slow introduction begins off the tonic on a dominant seventh chord that does not resolve to C major, deliberately obscuring the key.

Q2. Name the four main sections of the sonata-form Allegro con brio in order. [2 marks]

• Cue. Exposition, development, recapitulation, coda.

Q3. Explain how the orchestration and dynamics of this movement reflect both the Classical style and Beethoven's individual approach. [6 marks]

• What the marker wants. A Classical orchestra (paired woodwind, horns, trumpets, timpani, strings) with no continuo, homophonic melody-and-accompaniment writing with some imitation and antiphonal exchanges, in the manner of Haydn and Mozart; plus Beethoven's own energy in the sforzando accents, sudden dynamic contrasts and con brio drive that look ahead to the Romantic period.
