What this dot point is asking
SEAB wants you to describe the main features of Baroque style (roughly 1600 to 1750) and to explain the structure of the concerto grosso, the period's great orchestral form built on the contrast of a small solo group and the full ensemble. The central insight is that Baroque music thrives on contrast and continuity at once: a continuous bass and steady rhythm drive the music forward, while abrupt contrasts of force and texture give it shape.
The answer
The hallmarks of Baroque style
Several features mark music as Baroque:
- Basso continuo: a continuous bass line played by a low instrument (cello or bassoon) with a chordal instrument (harpsichord or organ) realising the harmony above it, present in almost every Baroque piece.
- Terraced dynamics: changes of volume in sudden steps (loud, then suddenly soft) rather than gradual crescendos, partly because the harpsichord cannot swell.
- Counterpoint: independent melodic lines woven together, the polyphonic texture that culminates in the fugue.
- Ornamentation: decorative notes (trills, mordents, appoggiaturas) added to melodies.
- A steady, driving rhythm: a constant rhythmic energy, often spinning out long lines of running notes.
The concerto grosso: forces
The concerto grosso is built on contrast between two bodies of players:
- The concertino: a small group of soloists (often two violins and continuo).
- The ripieno (or tutti): the full string orchestra with continuo.
The music passes back and forth between them, the small group playing intricate solo passages and the full group answering with weightier statements, a contrast heard as terraced dynamics.
Ritornello form
The fast outer movements typically use ritornello form. A bold orchestral theme, the ritornello, opens the movement and then returns several times, like a recurring chorus, between contrasting episodes for the concertino. The ritornello often comes back in different related keys before a final, complete return in the home key, giving the movement both variety and unity.
Texture and the trio sonata thread
Baroque chamber music often used the trio sonata layout (two melody instruments over continuo), the same small-group sound found in the concertino. Recognising this continuo-led, contrapuntal texture is one of the surest signs of the Baroque.
Examples in context
Example 1. A set of solo concertos depicting the seasons. A famous Baroque set of violin concertos uses vivid instrumental effects to suggest scenes of nature across the year, with a solo violin contrasted against the string orchestra and ritornello themes framing each movement. It shows how Baroque concerto writing pits soloist against ensemble while painting pictures in sound.
Example 2. A collection of concertos dedicated to a German margrave. A celebrated set of six Baroque concertos, each scored for a different combination of solo instruments against the strings, demonstrates the variety possible within the concerto-grosso idea, every work exploring a fresh concertino group while keeping continuo, counterpoint and ritornello structure.
Try this
Q1. List four features that mark music as Baroque. [4 marks]
- Cue. Basso continuo, terraced dynamics, counterpoint (polyphony), ornamentation, and a steady driving rhythm are all Baroque features (any four).
Q2. Define the concertino and the ripieno in a concerto grosso. [2 marks]
- Cue. The concertino is the small group of soloists; the ripieno (tutti) is the full ensemble, and the music alternates between them.
Q3. Explain what happens in ritornello form. [3 marks]
- Cue. A recurring orchestral theme (the ritornello) returns several times, often in different related keys, between contrasting episodes for the soloists, before a final return in the home key.

Original5 marksDescribe five features that would help you identify an extract as Baroque, explaining briefly how each would sound.Show worked answer →
Basso continuo: a continuous bass line with a chord-playing instrument (harpsichord or organ) filling in the harmony throughout.
Terraced dynamics: sudden steps between loud and soft rather than gradual crescendos, often heard when the full group answers a small group.
Counterpoint: two or more independent melodic lines woven together (polyphonic texture), as in a fugue.
Ornamentation: decorative notes such as trills and mordents added to the melody.
A steady, driving rhythm: a constant rhythmic pulse and energy, often with running quavers or semiquavers.
What markers reward: five genuine Baroque features each with a short audible description. Naming a feature without saying how it sounds (just counterpoint) earns less than counterpoint, several independent melodic lines woven together.
Original6 marksExplain the structure of a concerto grosso, defining the concertino, the ripieno and ritornello form, and describe how contrast is created.Show worked answer →
A concerto grosso sets a small group of soloists against the full ensemble. The small solo group is the concertino; the full body of strings (with continuo) is the ripieno (or tutti).
The first movement is usually in ritornello form: a recurring orchestral theme, the ritornello, returns between passages for the concertino. The ritornello often comes back in different related keys before a final return in the home key.
Contrast is created in several ways: between the small concertino and the large ripieno (a contrast of forces and volume, often heard as terraced dynamics), between solo display and orchestral statement, and between the stable ritornello theme and the more adventurous solo episodes.
What markers reward: correct definitions of concertino and ripieno, a clear account of ritornello form (a recurring tutti theme alternating with solo episodes, returning in different keys), and at least two genuine sources of contrast. The strongest answers link the small-versus-large contrast to terraced dynamics.
