What did the Classical orchestra consist of, and what textures and accompaniment figures define the style?
The Classical orchestra (its instrumentation and the rise of the piano) and the characteristic textures of the era (melody-dominated homophony, the Alberti bass, periodic phrasing and orchestral tutti), as examined in Area of Study 1.
A focused answer to the Classical orchestra and texture for OCR A-Level Music Area of Study 1. Covers the make-up of the Classical orchestra (strings, paired woodwind, horns, trumpets and timpani), the rise of the piano, and the characteristic textures (melody-dominated homophony, the Alberti bass, periodic phrasing, tutti and solo contrast), with how OCR examines sonority by ear.

What this dot point is asking
The sonority of Area of Study 1 is the Classical orchestra and the keyboard, and its textures are largely homophonic, built on idiomatic accompaniment figures and balanced phrasing. OCR examines instrumentation and texture in both the prescribed work (Section B) and unfamiliar extracts (Section A), so you must know the make-up of the Classical orchestra, the rise of the piano, and the characteristic textures, including the Alberti bass, that define the style.

How OCR examines sonority and texture
Section B asks you to describe the instrumentation and texture of passages in the prescribed work, including how the scoring changes (from solo or chamber to tutti). Section A asks you to name instruments, techniques and texture types in unfamiliar extracts, and may ask you to identify a keyboard accompaniment figure such as the Alberti bass. The marks come from specific, accurate naming of instruments and textures tied to the music, never from vague description.

Q1. List the instrument families of the Classical orchestra and a typical pairing within the woodwind. [Knowledge recall]
- Cue. Strings (violins, violas, cellos, double basses); woodwind in pairs (two flutes, oboes, clarinets, bassoons); brass (two horns, often two trumpets); percussion (timpani).
Q2. Why did the piano replacing the harpsichord matter to Classical expression? [Short explanation]
- Cue. The piano allows graded dynamics (crescendos, diminuendos, sudden loud-soft contrasts), which the harpsichord cannot, expanding the dynamic and expressive range of sonatas and concertos.

OCR 2019 (H543/05 Section B, style)4 marksDescribe the instrumentation and texture of the passage from the prescribed work. (Section B, prescribed work)Show worked answer →
Up to four marks. Name the instruments and forces (for example strings carrying the melody, paired woodwind doubling or answering, horns sustaining, timpani and trumpets reinforcing a tutti), and any techniques (pizzicato, tremolo, con sordino). Describe the texture precisely: melody-dominated homophony with an Alberti or repeated-chord accompaniment, a contrapuntal passage, antiphony between strings and wind, or a full tutti. Markers reward specific, accurate sonority and texture tied to the passage, including any change from solo or chamber scoring to full orchestra. They penalise vague answers ("lots of instruments", "thick texture") and wrong instrument families.
OCR 2022 (H543/05 Section A, style)3 marksIdentify the accompaniment figure in the left hand and describe its effect. (Section A, unfamiliar listening, keyboard extract)Show worked answer →
Up to three marks. Identify the figure: an Alberti bass (a broken-chord pattern, low-high-middle-high, outlining the harmony), a repeated-chord or "drum bass" accompaniment, or a broken-octave or arpeggiated figure. Describe its effect: the Alberti bass gives a light, even, flowing support that keeps the harmony clear without competing with the melody, idiomatic to Classical keyboard writing. Markers reward correct identification of the figure plus its textural effect. They penalise calling any left-hand part an Alberti bass, or describing it only as "the accompaniment" with no named figure.
