Welcome to Mozart's Symphony No. 39 (First Movement)
Welcome to your complete revision guide for Wolfgang Amadeus Mozart's Symphony No. 39 in \(E\flat\) major, K. 543 (First Movement: Adagio – Allegro). This work is a core set piece for CCEA AS Unit 3: Music for Orchestra, 1700–1900 (Specification 7010).
Whether you find score analysis straightforward or a little daunting, don't worry! We will break down every section, theme, instrument, and harmonic shift step by step so you can walk into both Paper 1 (Test of Aural Perception) and Paper 2 (Written Examination) with total confidence.
---1. Background, Context & Chronology
Let's look at the historical setting before diving into the notes:
- Composer: Wolfgang Amadeus Mozart (1756–1791).
- Date of Completion: June 26, 1788 (entered directly into Mozart's personal thematic catalogue).
- Catalogue Number: K. 543 (the "K" stands for Ludwig von Köchel, who catalogued Mozart's works chronologically).
- Historical Context: Symphony No. 39 is the first in Mozart's legendary final symphonic trilogy (Nos. 39 in \(E\flat\) major, 40 in G minor, and 41 in C major "Jupiter"), all written in rapid succession during the summer of 1788 in Vienna.
- Home Key: \(E\flat\) major (3 flats: \(B\flat\), \(E\flat\), \(A\flat\)).
Quick Memory Aid: Remember the year 1788 as Mozart's "Symphonic Summer" — three monumental masterpieces produced in just a few months!
Key Takeaway: Symphony No. 39 in \(E\flat\) major is a mature Classical masterpiece composed in Vienna in summer 1788 as the opening work of Mozart's final symphonic trilogy.
---2. Orchestration & Instrumentation
Examiners love asking about Mozart's scoring for this symphony because it contains one very unusual feature that catches many students out!
Orchestral Forces
- Woodwind: 1 Flute, 2 Clarinets (in \(B\flat\)), 2 Bassoons.
- Brass: 2 French Horns (in \(E\flat\)), 2 Trumpets (Clarini in \(E\flat\)).
- Percussion: Timpani (tuned to \(E\flat\) and \(B\flat\), the tonic and dominant).
- Strings: First Violins, Second Violins, Violas, Cellos, and Double Basses.
The Golden Rule of Instrumentation for K. 543
Notice anything missing? There are NO OBOES in this entire symphony! In a standard Classical orchestra, oboes were the primary soprano woodwind. Here, Mozart explicitly leaves them out and gives the spotlight to the warm, mellow tone of the clarinets in \(B\flat\).
Common Mistake to Avoid: Never write "oboes" when listing the woodwinds for Symphony No. 39. Mentioning oboes is an instant red flag to an examiner!
Transposing Instruments in the Score
When reading the score in Paper 2, keep transpositions clear:
- Clarinets in \(B\flat\): Sound a major 2nd lower than written.
- Horns in \(E\flat\) & Trumpets in \(E\flat\): Sound a major 6th lower (or minor 3rd higher depending on the octave register) than written in C.
Key Takeaway: Mozart scores for a standard Classical orchestra with one crucial change: oboes are omitted, making the clarinets the expressive leaders of the woodwind family.
---3. Form and Structure Overview
The first movement is cast in standard Sonata-Allegro Form, but it is introduced by an expansive, majestic Slow Introduction.
Think of Sonata Form like a three-act drama:
- Exposition (Act 1): The characters (themes) are introduced in two contrasting keys.
- Development (Act 2): The characters enter a period of conflict and adventure (modulations and motivic fragmentation).
- Recapitulation (Act 3): The characters return home, resolving all tension into the home key (\(E\flat\) major).
Let's also look out for the metre change: the slow introduction is in Cut time (\(\mathcal{C}\) or \(2/2\)), but the main Allegro shifts into triple metre (\(3/4\))!
---4. Detailed Structural & Thematic Analysis
A. The Slow Introduction (Adagio, Cut time / \(2/2\), \(E\flat\) major)
- Grand Opening Gesture: Opens with powerful, full orchestral (tutti) chords featuring heavy dotted rhythms interspersed with dramatic descending scale runs in the violins called tiratas. This grand texture is inspired by the Baroque French Overture style.
- Harmonic Journey: Built over solid tonic (\(E\flat\)) pedal points, the music soon ventures into expressive chromaticism, poignant dissonant suspensions, and diminished harmonies.
- Dominant Preparation: The introduction winds down quietly, hovering on a prolonged dominant (\(B\flat\)) chord, building anticipation before releasing into the Allegro.
B. The Exposition (Allegro, \(3/4\) time, \(E\flat\) major)
- First Subject (Theme 1, \(E\flat\) major):
A graceful, lyrical piano melody played by the 1st violins. It is smooth, stepwise, and features gentle appoggiaturas (leaning notes). The theme is warmly supported by woodwind doublings (clarinets, horns, and bassoons). - Transition / Bridge Passage:
The gentle mood is interrupted by an energetic, explosive forte tutti. Driven by continuous quaver and semiquaver motor rhythms, the music modulates away from the tonic towards the dominant key, \(B\flat\) major. - Second Subject (Theme 2, \(B\flat\) major):
Contrasts sharply with the first theme. Instead of a single lyrical line, this theme is a conversational dialogue. Motivic fragments are tossed playfully back and forth between the strings (violins) and woodwinds (flute and clarinets). - Codetta:
Brings the exposition to an exciting close using energetic cadential fanfares that firmly establish and confirm the dominant key (\(B\flat\) major). The entire exposition is then marked with repeat signs.
C. The Development
- Motivic Breakdown: Mozart takes short melodic motifs from the exposition themes and chops them into smaller building blocks.
- Tonal Instability: The music travels rapidly through a series of closely related and more distant keys.
- Texture & Dynamics: Features tight contrapuntal imitation between the woodwinds and strings, paired with sudden dynamic contrasts.
- Dominant Retransition: The development concludes with a dominant pedal / dominant prolongation on \(B\flat\), preparing the ear for the return of the home key.
D. The Recapitulation & Coda (\(E\flat\) major)
- First Subject: Returns triumphantly in the tonic key of \(E\flat\) major, featuring subtle variations in orchestration.
- Transition (Modified): Harmonically re-routed! Instead of modulating to the dominant, it twists and turns to keep the music rooted in the tonic key.
- Second Subject: Returns in full, but this time it is transposed into the home tonic key of \(E\flat\) major (satisfying Classical tonal balance).
- Coda: A decisive, jubilant finishing section that reinforces \(E\flat\) major with robust tutti fanfare cadences.
Key Takeaway: The movement moves from a stately French Overture-style Adagio in \(2/2\) to a dance-like Allegro in \(3/4\), following strict Classical Sonata Form with themes moving between \(E\flat\) major and \(B\flat\) major.
---5. Sonata Form Tonal Roadmap (Summary Table)
Use this simple roadmap to memorize the tonal structure of the movement:
1. Introduction (Adagio, \(2/2\)): Starts in \(E\flat\) major \(\rightarrow\) ends on dominant preparation (\(B\flat\)).
2. Exposition (Allegro, \(3/4\)):
• 1st Subject: \(E\flat\) major (Tonic)
• Transition: Modulates \(E\flat \rightarrow B\flat\)
• 2nd Subject: \(B\flat\) major (Dominant)
• Codetta: Confirms \(B\flat\) major
3. Development: Unstable harmonies, modulations, dominant retransition on \(B\flat\).
4. Recapitulation & Coda (\(E\flat\) major):
• 1st Subject: \(E\flat\) major (Tonic)
• Transition: Adjusted to stay in Tonic
• 2nd Subject: \(E\flat\) major (Tonic)
• Coda: Firmly in \(E\flat\) major
6. Pitfalls & Examiner Tips for CCEA AS 3
Make sure you don't lose easy marks on these common exam traps:
- The Missing Oboes: Never list oboes in the orchestration. Clarinets in \(B\flat\) take over the primary upper-woodwind duties.
- Time Signature Confusion: The Adagio introduction is in Cut time / duple metre (\(2/2\) or \(\mathcal{C}\)), while the main Allegro switches to triple metre (\(3/4\)).
- Key of the Second Subject: In the Exposition, the 2nd subject is in the Dominant (\(B\flat\) major). In the Recapitulation, it returns in the Tonic (\(E\flat\) major).
- French Overture Reference: When describing the introduction in extended writing, always mention the dotted rhythms and descending violin scale runs (tiratas) as hallmarks of the French Overture style.
