10.3 Bach's contrapuntal techniques and compositional style

Bach's contrapuntal techniques are the backbone of his musical genius. From canons to fugues, he mastered intricate forms that weave melodies together in complex patterns. These methods appear across his keyboard works, chamber music, orchestral pieces, and sacred compositions.

Bach's style goes beyond counterpoint, incorporating ornate melodies, rhythmic complexity, and rich harmonies. His mastery influenced generations of composers and set a high bar for contrapuntal writing. Bach's works continue to inspire and challenge musicians to this day.

1 of 3

• Canon involves a melody imitated by one or more voices after a fixed duration
  • Round canon has all voices enter at the same pitch level (Row, Row, Row Your Boat)
  • Crab canon plays the melody in retrograde (backwards) in the second voice (Bach's Musical Offering)
• Fugue is a contrapuntal composition with a principal theme (subject) introduced by one voice and subsequently taken up by others
  • Exposition introduces the subject in each voice
  • Episode passages occur between subject statements, often featuring subject or countersubject fragments
  • Stretto overlaps subject entries, creating increased tension (Fugue in C minor from The Well-Tempered Clavier Book 1)
• Invertible counterpoint allows two or more melodies to be interchanged as either top or bottom voice
  • Ensures harmonically and melodically coherent counterpoint regardless of voice order (Contrapunctus IV from The Art of Fugue)

Counterpoint across Bach's genres

• Keyboard works showcase Bach's mastery of counterpoint
  • The Well-Tempered Clavier contains preludes and fugues in all 24 major and minor keys
  • Goldberg Variations employ various contrapuntal techniques in 30 variations on a single aria
• Chamber music demonstrates complex contrapuntal techniques
  • The Art of Fugue is an incomplete collection of fugues and canons
  • Musical Offering includes canons and fugues based on a theme by Frederick the Great
• Orchestral works integrate contrapuntal elements
  • Brandenburg Concertos feature intricate interplay between soloists and orchestra
  • Orchestral suites incorporate counterpoint into dance forms (Overture in the French Style)
• Sacred music incorporates various contrapuntal techniques
  • Mass in B minor is a monumental work with fugues and canons
  • Motets demonstrate Bach's skill in writing intricate counterpoint for multiple voices (Singet dem Herrn ein neues Lied)

Compositional Style

Elements of Bach's compositional style

• Ornamentation adds expressiveness and variety to melodies
  • Trills, mordents, and turns are embellishments (Aria from Goldberg Variations)
  • Appoggiaturas and suspensions create tension and release with dissonant notes resolving to consonant ones
• Rhythmic complexity creates forward motion and interest
  • Syncopation emphasizes weak beats or off-beats (Prelude in C# minor from The Well-Tempered Clavier Book 1)
  • Polyrhythms use contrasting rhythmic patterns simultaneously in different voices
• Harmonic language employs tonal harmony, chromaticism, and modulation
  • Tonal harmony uses major and minor keys with clear tonic-dominant relationships
  • Chromaticism incorporates notes outside the prevailing key for tension and color (Chromatic Fantasy and Fugue)
  • Modulation shifts from one key to another, often to closely related keys

Impact of Bach's contrapuntal mastery

• Elevated contrapuntal techniques as a fundamental aspect of compositional craft
• Demonstrated potential for emotional expression and musical complexity within counterpoint
• Influenced later composers like Mozart, Beethoven, and Brahms who studied and incorporated Bach's techniques
• Established a benchmark for contrapuntal mastery that continues to inspire and challenge composers today (Shostakovich's 24 Preludes and Fugues)
