The three eras at a glance (1650–1910)
A tradition is a way of making music that is passed down and slowly changed. The Western classical tradition is music written down in notation, mostly for churches, royal courts, opera houses and public concerts in Europe.
- Baroque (about 1600/1650–1750): ornate, energetic, driving rhythm, one mood per movement.
- Classical (about 1750–1820): clear, elegant, balanced; question-and-answer phrases.
- Romantic (about 1820–1910): emotional, dramatic, big contrasts, longer and freer forms.
How to listen: ask four questions. How many players? Is there a harpsichord? Does the loudness jump or grow? Is the tune short and balanced or long and sweeping? Dance changed too: courtly minuets in the Baroque and Classical eras, then the waltz and ballet grew in the Romantic era.
Try it: play any short Vivaldi, Mozart and Chopin piece. For each, tick the four questions above. Then check your guess in free play.
Baroque music and the solo concerto
Key features: basso continuo (a bass line plus harpsichord or organ chords), terraced dynamics (loud and soft change suddenly, like stairs), ornaments (trills and decorations), sequences (a short idea repeated higher or lower), and polyphony in fugues.
The solo concerto
A concerto is a piece for one soloist and an orchestra. The Baroque solo concerto usually has three movements: fast – slow – fast. Fast movements often use ritornello form: the full orchestra (tutti) plays a returning theme, and the soloist plays showy episodes in between. Composers: Vivaldi (violin concertos such as The Four Seasons), Bach, Corelli, Torelli.
Other Baroque forms
Concerto grosso (a small group against the orchestra), suite of dances, fugue, oratorio (like Handel's Messiah) and early opera.
Classical music, sonata form and Mozart's operas
Key features: homophony (a tune with chords underneath), balanced phrases (often 4 + 4 bars), Alberti bass (broken chords in the left hand), gradual crescendo and diminuendo, a standard orchestra (strings, pairs of woodwind, horns, trumpets and timpani). The piano replaces the harpsichord.
Sonata form
- Exposition: first theme in the tonic (home key); a bridge; second theme in a new key (dominant, or relative major if the piece is minor).
- Development: ideas are broken up and moved through many keys.
- Recapitulation: both themes return, now both in the tonic; a coda ends the movement.
Beethoven's Symphony No. 1 (1800), movement 1, is a good study piece. A slow introduction starts on a surprising chord away from the home key. Then comes a fast sonata-form movement in C major for a Classical orchestra. Beethoven's bold accents and sudden loud chords point towards Romanticism.
Mozart's operas
An opera is a drama that is sung. Parts: overture (orchestral opening), recitative (speech-like singing that moves the story), aria (a solo song that shows feeling), and ensembles (duets, trios and finales where characters sing different things at once). Mozart wrote comic opera (opera buffa: The Marriage of Figaro, Don Giovanni, Così fan tutte) and German Singspiel with spoken dialogue (The Magic Flute). Each character gets their own style of tune.
Romantic music and the piano (Chopin, Brahms, Grieg)
Key features: huge orchestras (extra brass, harp, many percussion), very wide dynamics (ppp to fff), rubato (stretching and squeezing the tempo for feeling), chromatic chords (notes outside the key), long singing melodies, programme music (music that tells a story or paints a picture) and nationalism (using folk tunes and dances of a homeland).
The Romantic piano
The piano got an iron frame, so it became louder and stronger. It moved into homes and concert halls. Composers wrote short character pieces:
- Chopin (Poland): nocturnes (night songs), mazurkas and polonaises (Polish dances), études; singing melody, rubato, pedal.
- Brahms (Germany): intermezzos, rhapsodies, ballades; thick, warm chords and cross-rhythms (3 against 2).
- Grieg (Norway): Lyric Pieces; Norwegian folk dances, drones and simple, fresh tunes.
Key formulas and definitions
- Baroque 1650–1750: basso continuo, terraced dynamics, ornaments, concerto (fast–slow–fast), ritornello, fugue
- Classical 1750–1820: homophony, balanced phrases, Alberti bass, crescendo, symphony, sonata form
- Romantic 1820–1910: huge orchestra, rubato, chromatic chords, programme music, nationalism
- Sonata form = Exposition (T1 tonic, T2 new key) → Development → Recapitulation (both tonic) → Coda
- Opera = overture + recitative (story) + aria (feeling) + ensembles
- Tutti = whole orchestra; solo = one player
- Rubato = flexible tempo for expression
Worked examples
1. You hear violins, a harpsichord tinkling all the way through, a solo violin that keeps alternating with the full group, and loudness that jumps between loud and soft. Era and form?
Harpsichord continuo + terraced dynamics → Baroque. Solo vs full group with a returning theme → solo concerto in ritornello form (for example a Vivaldi violin concerto).
2. A movement opens with theme A in C major, then theme B in G major. In the middle the music wanders through many keys. Later A and B both return in C major. Name the form and each part.
Sonata form. Exposition: A (tonic, C) and B (dominant, G). Development: wandering through keys. Recapitulation: A and B both in the tonic C. A short coda may close.
3. A solo piano piece slows down and speeds up freely, uses many notes outside the key, a long singing tune and a Polish dance rhythm. Who might have written it, and why?
Rubato, chromatic harmony and a singing tune are Romantic. A Polish dance (mazurka or polonaise) points to Chopin, who used his homeland's dances: Romantic nationalism.
Common mistakes
- Calling all orchestral music "classical". The Classical era is only about 1750–1820.
- Saying Baroque music uses crescendos. Baroque loudness mostly changes suddenly (terraced); the smooth crescendo is a Classical habit.
- Thinking the recapitulation is the same as the exposition. In the recap the second theme moves into the home key.
- Mixing up aria and recitative. Recitative moves the story with speech-like singing; an aria stops to show feeling.
