Chapter 10 Baroque Instrumental Music Key Terms • • • • • • • Concerto Concerto grosso Movement Ritornello Ritornello form Variation form Ground bass (basso ostinato) The Rise of Instrumental Music • Required new understanding between composers and audiences – When to end a piece? – How to make instrumental works coherent? – How to sustain interest and drama? The Rise of Instrumental Music (cont’d.) • Length – With vocal music, text ends – With instrumental, form or genre determines length • Coherence – Begin and end in same key – Use repetition, return, sequence, and imitation • Sustaining interest – Use contrast and variation – Modulate to other keys – String contrasting movements together Concerto and Concerto Grosso • The most important orchestral genres of the Baroque era • Underlying idea is contrast – Soloist against orchestra – Group of soloists against orchestra – Virtuosity, brilliance against power, stability Movements • Movement = Self-contained section of a larger work • Typical concerto has three – I: Bright, extroverted, fast – II: Slower, quieter, more emotional – III: Similar to I, often faster Ritornello Form • Based on contrast of musical ideas – Orchestral material (ritornello) – Solo material • Returns many times to a stable element – In whole or in part – In various keys – Usually in full and in tonic key to end piece Standard Ritornello Form RIT = Complete ritornello statement [RIT] = Partial ritornello statement Solo 1, 2, 3, etc. = Solo episodes Ritornello vs. Episode Ritornello • Principal theme • Solid and forceful • Often very tuneful • For full orchestra • Ends in tonic with strong cadence • Familiarity grows with each return Solo episode • Contrasting section • Faster, more brilliant • Free and virtuosic • For soloist(s) • Modulates, flows into next ritornello • Always something new and surprising Antonio Vivaldi (1678–1741) • “Red Priest,” famous as virtuoso violinist, composer, and teacher – Wrote over 400 concertos – Renowned for quality of teaching – Famous for student concerts • Toured frequently throughout Europe • Settled in Vienna near end of his life Vivaldi, Violin Concerto in G • Opus 4 = Fourth published set of concertos • La stravaganza = Descriptive title of set • No. 12 = Concerto’s number within the set • Standard three-movement format – I and III fast and brilliant, in ritornello form – II slower and gentler, in ground bass form Violin Concerto in G, I • Ritornello theme (for orchestra) – Three short sections (a, b, c) – Alternates between first and second violins Concerto in G, I • Only ritornello 1 uses entire theme • Solos become progressively freer and virtuosic • Ritornellos and solos swap roles at times! • Ends with literal return of ritornello (b, c) Baroque Variation Form • Simultaneous repetition and contrast • Short theme repeated and varied over basso ostinato – Dynamics, tone color, harmonies often changed – Less often, tempo, key, and mode • Other names: passacaglia, chaconne, ground bass form Violin Concerto in G, II • Contrasting slow movement in variation form • Continuity – Repetition of ground bass – Dominant harmony at end of ground bass pulls to tonic in next repetition • Variety – Gradually faster solo figuration in variations 1–4 – Sudden, dramatic changes in 5–6 Violin Concerto in G, II • Overall ternary feel (A B A) – Theme and variations 1–4 • Entirely in G major, basso ostinato – Variations 5–6 • Shifts to G minor, ostinato moves to violins, continuo drops out – Final statement of original theme Violin Concerto in G, III • Fast tempo, ritornello form • Form even freer than in movement I – Solo introduction – First ritornello statement interrupted by solo – Second ritornello presents new theme – Solo violin jumps from one idea to another • Ritornellos 3 and 5 provide stability Concerto Grosso • Concerto for a group of solo instruments and orchestra • Otherwise similar to concerto – Three movements: fast, slow, fast – Fast movements usually ritornello form – Emphasis on contrast (contest) between soloists and orchestra J. S. Bach (1685–1750) • From family of musicians • First a church organist, later a court composer • 1723—Cantor and Director musices, Leipzig • Prolific, wrote in almost every genre Bach, The Brandenburg Concertos • Set of six concertos by Bach • Gift to Margrave of Brandenburg, 1721 • Each uses a different group of solo instruments – Unusual combinations – Dazzling tone colors – Imaginative contrasts between soloists and orchestra Brandenburg Concerto No. 5 • Solo group = Flute, violin, harpsichord • Some soloists do double duty – Violin leads orchestra in ritornellos – Harpsichord provides continuo chords • Standard three-movement format Brandenburg Concerto No. 5, I • Allegro movement in ritornello form • Extended movement—nearly 10 minutes • To sustain interest, Bach introduces progressively more dramatic contrasts Brandenburg Concerto No. 5, I • Ritornello theme – Homophonic feel – Complete theme only at beginning and end – Three subsections (a, b, c) – Complex, irregular rhythms, melodic contour, and phrase lengths Brandenburg Concerto No. 5, I • Solo episodes – Solo group with continuo – Rich, imitative polyphony – Progressively more dramatic contrasts (central solo and cadenza) • Cadenza = Improvised solo passage – Typically near end of concerto’s first movement – This one unusually long for 1721 Key Terms • • • • • Fugue Subject Exposition Subject entries Episodes • • • • • Countersubject Inversion Stretto Prelude Arpeggio Fugue • Most characteristic form of Baroque music • Systematized imitative polyphony – Polyphonic composition for a fixed number of instrumental lines or voices – Built on a single principal theme (subject) – Subject “chased” from one voice to another Typical Fugue • Exposition • Alternating episodes and subject entries Fugal Exposition • The subject = The principal theme • All voices take turns presenting the subject in full • Each voice continues with new material as next one states subject Episodes and Subject Entries • Subject reenters at intervals – In any voice – In different keys • Episodes contrast with subject entries • Final subject entry in tonic key Subject Entries vs. Episodes Subject entries • Fixed—always recognizable as subject • Stable—in one key for each statement • May occur in different keys after episodes Episodes • Free—may explore motives from subject in any order • Unstable—modulate from one key to another • Connect subject entries that are in different keys Bach, The Well-Tempered Clavier • A testament to Bach’s fugal skill • Book 1 (1722) and Book 2 (1744) • Each presents a fugue in every key, both major and minor (48 total) • Each fugue preceded by a prelude Bach, Prelude 1 in C Major • Upward-moving arpeggio • Rich succession of chords • Some dissonant harmonies Bach, Fugue 1 in C Major • No episodes, no countersubject • 24 entries of the subject • Stretto Key Terms • • • • • • • Dance suite Minuet Sarabande Gigue Binary form Trio Tambourin The Dance Suite • A grouping of miscellaneous dances – All in same key – Last dance always fast • Usually stylized dances – Written for listening, not dancing – Allow greater musical sophistication • Written for various performing forces – Orchestra, chamber ensembles, solo harpsichord or lute Baroque Dances • Each dance characterized by – Specific dance steps – A certain meter – A distinctive tempo – Unique rhythmic features Baroque Dance Form • Binary form: two sections (a, b) – Each ends with strong cadence – Each is repeated (a a b b) – Symmetrical feel—shared motives, cadences, etc. – b usually longer than a • a a b b or |: a :||: b :| Dance and Trio • Larger-scale A B A form – Groups two shorter dances of same type (A) – Contrasting middle dance is the trio (B) – Minuet and trio, gavotte and trio, etc. • Trio is softer and lighter than A dance – Uses different melody and rhythms • Return of A creates satisfying conclusion Rameau, Menuet and Tambourin from Castor et Pollux • No trio for the minuet • Instead, fast tambourin • Form |: A :| |: B :| 8 16 Handel, Minuet from Royal Fireworks Music • Composed to celebrate the end of the War of the Austrian Succession • Not meant to be danced Bach, Gigue from Cello Suite No. 2 in D Minor • Part of a set of six suites for solo cello • Bowing on two adjacent strings • Form |: a :| |: b :|
