What this dot point is asking
SEAB wants you to account for the defining features of the Baroque style (roughly 1600 to 1750) and to explain how a fugue is constructed. The central insight is that the Baroque is built on the basso continuo and on functional counterpoint, and that the fugue is the most systematic expression of Baroque contrapuntal thinking, growing an entire piece from one subject.
The answer
The musical concept: hallmarks of the Baroque style
- Basso continuo: the foundation of almost all Baroque ensemble music. A continuous bass line is played by a bass instrument (cello, viol, bassoon) while a chordal instrument (harpsichord or organ) fills in the harmony from a figured bass.
- Terraced dynamics: abrupt changes between loud and soft levels rather than gradual crescendos, reflecting the harpsichord and organ.
- Motoric rhythm: continuous, driving rhythmic motion that spins out a rhythmic motor across a movement (Fortspinnung).
- Functional harmony and sequence: clear tonal harmony with frequent sequences and strong cadences.
- Ornamentation: trills, mordents, appoggiaturas and other decorations, often improvised.
- Texture: either imitative polyphony or a melody supported by continuo.
Named repertoire and forms
Characteristic Baroque genres include the concerto (Vivaldi, Bach's Brandenburg Concertos), the suite of dances, the trio sonata, and the fugue. Bach, Handel and Vivaldi are the central figures.
The technique: how a fugue is constructed
A fugue is a contrapuntal composition built on a single theme:
- Subject: the main theme, stated alone at the start in one voice.
- Answer: the subject restated in another voice, usually a fifth higher (in the dominant). A real answer transposes it exactly; a tonal answer adjusts an interval to keep the tonality.
- Countersubject: the recurring counterpoint that accompanies the answer and later entries.
- Exposition: the opening section in which every voice enters with the subject or answer in turn.
- Episode: a passage between entries, usually sequential and modulatory, built from fragments of the material.
- Middle and final entries: further statements of the subject in related keys.
- Stretto: overlapping entries, where a new statement begins before the previous one finishes, intensifying the texture near the end.
- Pedal point: a sustained bass note (often the dominant) under shifting harmony, frequently signalling the approach to the final cadence.
Examples in context
Example 1. J.S. Bach, The Well-Tempered Clavier. The collection of preludes and fugues in every key is the definitive corpus for studying fugal construction: subjects answered in turn, countersubjects, episodes, stretto and pedal points, all over functional harmony. It demonstrates the contrapuntal heart of the Baroque.
Example 2. Vivaldi, The Four Seasons. These violin concertos display Baroque ritornello form, motoric rhythm, terraced dynamics and continuo-supported textures, with the solo violin set against the ripieno. They show the Baroque concerto idiom alongside Bach's fugal writing, the two pillars of the style.
Try this
Q1. Explain what the basso continuo is and which instruments typically play it. [2 marks]
- Cue. The basso continuo is a continuous accompanying bass: a bass instrument (such as cello or bassoon) plays the bass line while a chordal instrument (harpsichord or organ) realises the harmony from a figured bass.
Q2. Define the subject and answer in a fugue. [2 marks]
- Cue. The subject is the main theme stated alone at the start (in the tonic); the answer is its restatement in another voice, usually a fifth higher in the dominant.
Q3. What is a stretto, and what effect does it create in a fugue? [3 marks]
- Cue. A stretto is the overlapping of subject entries, where a new statement begins before the previous one ends; it tightens and intensifies the texture, typically building toward the climax near the end of the fugue.

Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Original8 marksYou hear a keyboard piece in which a single melodic idea is announced alone, then restated a fifth higher while the first line continues with a steady contrasting melody, and the same idea then enters in lower and higher voices in turn. After all voices have entered, a passage based on fragments of the idea modulates before the idea returns. Identify the genre and explain the function of each element you hear.Show worked answer →
Identify the genre. Successive entries of one idea in each voice, with continuing counterpoint, identify a fugue, the central contrapuntal genre of the Baroque.
Explain the elements. The opening idea stated alone is the subject. Its restatement a fifth higher (in the dominant) is the answer; if the intervals are adjusted to fit the key it is a tonal answer, otherwise a real answer. The steady contrasting melody against the answer is the countersubject. Once every voice has entered, the exposition is complete. The passage on fragments that modulates is an episode (developmental, often sequential). The later return of the subject is a middle or final entry.
Markers reward correct use of subject, answer, countersubject, exposition and episode, and a clear account of each element's role. A strong answer adds stretto (overlapping entries) or a pedal point if heard, and names a likely composer (Bach).

List and explain the features. Basso continuo: a continuous bass line played by a bass instrument (cello, bassoon) plus a chordal instrument (harpsichord, organ) realising the harmony from figured bass. Terraced dynamics: sudden shifts between loud and soft rather than gradual crescendos, partly because of harpsichord and organ construction. Motoric rhythm: continuous, driving note values that spin out a single rhythmic motor. Texture: often polyphonic and imitative, or melody-and-continuo. Harmony: functional, with clear cadences and frequent sequences. Ornamentation: trills, mordents and appoggiaturas, often improvised.
Use examples. Vivaldi concertos for ritornello and motoric drive; Bach fugues and Brandenburg Concertos for counterpoint and continuo; Handel for grand choral writing.
Evaluate. Markers reward each feature correctly explained, the central role of the continuo, and located examples. The strongest answers connect the features (for instance, how the continuo underpins both solo and tutti textures).
