Welcome to Bernstein: "Tonight (Quintet)" from West Side Story
Welcome to your study guide for one of the most thrilling ensemble pieces in 20th-century musical theatre! In Unit AS 3 (Area of Study: Secular Vocal Music – Musicals), you will explore how Leonard Bernstein creates dramatic tension and character contrast using advanced musical techniques. Don't worry if musical analysis feels challenging at first; we will break down the piece layer by layer, looking at melody, rhythm, texture, harmony, and orchestration so that you feel fully confident in your exam.
1. Background and Dramatic Context
Title: "Tonight (Quintet)"
Musical: West Side Story (first staged on Broadway in 1957)
Music: Leonard Bernstein
Lyrics: Stephen Sondheim
What is Happening in the Story?
This number takes place near the end of Act 1, immediately before the "Rumble" (a deadly street fight arranged between two rival teenage gangs in New York City). It functions as a dramatic montage. Instead of showing events one after another, Bernstein weaves together the contrasting expectations of five different viewpoints on what will happen "tonight":
• The Jets: The American gang, led by Riff, looking forward to defeating their rivals in the fight.
• The Sharks: The Puerto Rican gang, led by Bernardo, equally determined to conquer the Jets.
• Anita: Bernardo's girlfriend, excitedly anticipating a romantic, passionate evening with Bernardo after the rumble.
• Tony: Former co-leader of the Jets, who has fallen deeply in love with Maria and longs to see her tonight.
• Maria: Bernardo's sister, who is hopelessly in love with Tony and dreams of their secret meeting.
Did You Know? Although many performers sing this number on stage, it is specifically classified on the CCEA syllabus as a "Quintet" because it represents exactly five distinct dramatic perspectives.
Key Takeaway: The "Tonight (Quintet)" is a dramatic montage set right before the Rumble, capturing five simultaneous, conflicting human emotions: gang aggression, romantic anticipation, and sultry passion.
2. Structure and Character Themes
Bernstein builds the quintet using a brilliant architectural design. The piece begins with isolated sections where each character or gang presents their own unique musical theme. Gradually, Bernstein layers these themes on top of each other, building to a thrilling, complex climax.
The Gangs: The Jets and The Sharks
• Mood & Style: Aggressive, tense, and edgy.
• Musical Features: Fast, heavily syncopated vocal lines, short punchy phrases, and unison or homophonic group singing.
• The "Vamp": Driven by a repetitive, rhythmic bass pattern called an ostinato or vamp, which builds an underlying sense of nervous anticipation.
Anita
• Mood & Style: Sultry, confident, and seductive.
• Musical Features: A slower, Latin-inflected "kick" theme. Her melody is expressive and rhythmically free, contrasting sharply with the stiff aggression of the gangs.
Tony and Maria
• Mood & Style: Lyrical, soaring, and intensely romantic.
• Musical Features: Smooth, legato lines carrying the famous "Tonight" melody. This theme stands out because it opens with the interval of a Perfect 4th, giving it an open, hopeful, and expansive quality.
The Climax: Polyphonic Superimposition
In the final section of the piece, Bernstein does something extraordinary: all five musical strands occur at the very same time. What began as separate homophonic or unison statements transforms into a rich, complex polyphonic (contrapuntal) texture. Each character sings their own unique words, rhythms, and melodies simultaneously, yet the harmony fits together with absolute precision.
Key Takeaway: The piece moves from separate character sections (homophonic/unison) into a massive polyphonic texture where five distinct melodies and lyrics are sung simultaneously.
3. The "Bernstein Style" & Musical Elements
Bernstein combined Broadway show tunes with classical compositional techniques and jazz rhythms. Here are the core musical trademarks you need to recognize:
A. Melodic Fingerprints: Tritone vs. Perfect 4th
• The Tritone (Augmented 4th / Diminished 5th): This is the overarching melodic "fingerprint" of the entire musical West Side Story. It is an unstable, dissonant interval that symbolizes the deep-rooted tension and hatred between the two gangs.
• The Perfect 4th: In contrast to the tense tritone, the romantic "Tonight" theme used by Tony and Maria prominently features the uplifting interval of a Perfect 4th.
B. Rhythm and Metre
• Syncopation: Accents placed off the main beats give the gang sections their restless energy.
• Ostinato / The Vamp: Repetitive bass riffs drive the momentum forward.
• Sudden Metre and Tempo Changes: Bernstein shifts time signatures and tempos to mirror shifts in dramatic tension.
C. Harmony and Tonality: Bitonality
• Bitonality: Bernstein frequently uses bitonality—the simultaneous use of two different keys at the same time. Clashing tonal strata (such as ideas based in C major sounding against ideas in F# major, which sit a tritone apart) musically depict the irreconcilable conflict between the Jets and the Sharks.
D. Orchestration and Timbre
• Brass & Percussion: Used forcefully with sharp accents to depict gang hostility and impending violence.
• Strings: Provide a warm, expressive, lyrical cushion for Tony and Maria's romantic themes.
• Piano: Drives the rhythmic pulse and emphasizes the low, punchy bass vamp.
Key Takeaway: Bernstein's signature sound in this piece relies on the contrast between the dissonant tritone and lyrical perfect 4th, rhythmic vamps with syncopation, clashing bitonality, and expressive orchestration tailored to each character.
4. The CCEA Aural Analysis Framework
When answering aural perception or written questions for CCEA AS Level Music, always organize your thinking using the standard elements of music. Here is how to break down the "Tonight (Quintet)":
1. Melody
• Gangs use short, fragmented, rhythmic, and angular motifs.
• Tony and Maria sing expansive, lyrical, arched melodies featuring the Perfect 4th interval.
• The tritone interval appears across the wider work as a unifying melodic motif for tension.
2. Rhythm and Metre
• Driving ostinato (vamp) in the bass creating continuous dramatic momentum.
• Heavy use of syncopation, off-beat accents, and sudden tempo/metre shifts to heighten excitement.
3. Texture
• Begins with alternating homophonic or unison sections for individual characters/gangs.
• Concludes with a complex polyphonic (contrapuntal) texture where all five vocal parts are superimposed simultaneously.
4. Harmony and Tonality
• Dramatic use of bitonality (e.g., contrasting keys like C major and F# major placed against one another).
• Dissonance and unresolved chords mirror the unresolved gang hostility.
5. Instrumentation and Dynamics
• Contrasting dynamics: soft, hushed murmurs of anticipation (pianissimo) building to a thunderous, dramatic climax (fortissimo).
• Orchestral division: Punchy brass and piano for gang tension; warm, sweeping strings for the lovers.
Key Takeaway: Always structure your exam answers through the five core elements: Melody, Rhythm, Texture, Harmony, and Instrumentation/Dynamics.
5. Top Exam Pitfalls to Avoid
Examiners note several common traps that cost students marks on this set work. Make sure you avoid these:
• Pitfall 1: Telling the Story instead of Analyzing the Music.
Incorrect: "The Jets are really angry because they want to beat up the Sharks tonight."
Correct (Analytical): "Bernstein conveys gang aggression through fortissimo brass, sharp syncopations, and a low, driving rhythmic vamp in the bass."
• Pitfall 2: Confusing the Intervals.
Remember that the opening leap of the "Tonight" melody is a Perfect 4th. The Tritone (augmented 4th / diminished 5th) is the tension motif used across the musical (such as in the theme for "Maria").
• Pitfall 3: Forgetting the "Vamp".
Do not overlook the repeating rhythmic figure in the accompaniment. Calling it an ostinato or vamp demonstrates accurate musical terminology.
• Pitfall 4: Mislabeling the Texture.
Do not call the whole piece polyphonic. It starts in separate, largely homophonic and unison blocks, and only becomes polyphonic when the themes are superimposed at the climax.
