Berlioz · Symphonie Fantastique (Movement 1)

Passions - Allegre

3 min readLast updated November 2026

Dynamics

  • Extremely wide range: pp → fff; frequent sfz markings. - Stravinsky's Rite of Spring uses sudden dynamic changes
  • Rapid contrasts within short passages: mf → pp → ff → ppp.
  • Crescendos and diminuendos - emphasise emotional intensity.

Rhythm / Tempo / Metre

  • In 2/2 - makes it 4 4 times faster
  • Allegro passages - fast, agitated, passionate.
  • Huge variety of note durations; dotted rhythms throughout.
  • Continuous quaver passages; syncopation prominent (bar 410 – syncopated Idée fixe).
  • Features
    • three-beat rest;
    • bars 78–79: heartbeat motif.
  • Markings
    • a tempo con fuoco
    • moto perpetuo.
  • Long tied semibreves at the end contrast frenetic sections.

Texture

  • Predominantly melody-dominated homophony.
  • Exceptions:
    • Monophonic in the Beginning of Idée fixe: flute and violin double
    • Homorhythmic homophony.
    • Plagal Amen: homophonic and homorhythm.
    • Antiphony : melody split between violin and full ensemble
    • Anti Texture - 3 bars of silence
    • Second iteration: octave textures.
    • Figure S: ascending/descending homophonic chromatic scales create drama.
  • Oboes carry melody; double basses provide crotchet rhythm.

Structure

Sonata form present but treated flexibly: story/content over formal rules.
  • Sections:
    • Introduction: bars 64–71
    • Exposition: bars 72–167
      • First Subject (Idée fixe): 72–111
      • Bridge: 111–149
      • Second Subject: 150–167
    • Development: bars 166–231
    • Recapitulation: bars 232–308
    • Coda: bars 329–525
  • Sonata form unconventional - plot guides structure.
  • Characterisation via subjects: first subject “masculine,” second subject “feminine” but aspiring toward first subject.

Melody

  • Idée fixe - rising enthusiasm → falling → repeated attempts to ascend.
  • First presented in flute and violin; irregular phrasing - conveys instability, yearning, unpredictability.
  • Conjunct motion with expressive leaps (6ths and 7ths) – emotional turbulence.
  • Chromaticism - obsession, restlessness, searching.
  • Dotted rhythms - yearning quality.
  • Begins on dominant G: perfect 4th → major 6th → descending.
  • Second subject: similar ascending/descending gesture; related to Idée fixe.
  • Sighing motif - emotion, resignation.
  • Heartbeat motif: protagonist’s emotional response.
  • Appoggiaturas: semitone movements (bars 152–154).

Instrumentation (Sonority)

  • Precise articulation and detailed score markings. - Stravinsky's Rite of Spring expands on these techniques significantly in the 20th century
  • Pizzicato, arco, senza sordina (without mute).
  • Tremolo - creates anticipation and tension.
  • Specific player references (e.g. first violin desk).
  • Double stopping (double corde) – bar 121.
  • Timpani: bar 329 – baguettes d’éponge; bar 64 – baguettes du recouvert en peau.

Tonality

  • Broadly C major and G major .
  • 1st subject (Idée fixe): C major
  • Bridge moves C → G.
  • 2nd subject: G major.
  • Chromaticism hides tonality
    • Chromatic deviations:
      • F minor;
      • D♭ minor;
      • D♯ major → E minor → restored G.
  • Bars 290–295: three perfect cadences establish tonality.
  • Recapitulation: 2nd subject remains in G - defying Classical expectations.
  • Coda: mostly C major; chromatic bassline and occasional A major chord obscure tonal certainty.
  • Bar 451: Idée fixe in C major (flute), followed by C minor (oboe) – narrative over rules.
  • Bars 511–end: plagal cadence IV → I.

Harmony

  • Functional harmony with chromatic colouring - for drama.
  • Bars 122–123: conventional 4-4-3 prepared dissonance.
  • Cadential suspensions.
  • Bar 143: cycle of fifths – conventional device.
  • Persistent dominant 7th patterns.
  • Numerous perfect cadences; ending includes plagal cadence.
