The cadenza is a unique and highly expressive component found in many classical concertos, including those written for the viola. This article delves into the fascinating world of cadenzas, particularly for two prominent viola concertos in the core repertoire: the Viola Concerto by William Walton and the Viola Concerto by Béla Bartók. We will explore the history, function, and performance aspects of these cadenzas, providing insights for both performers and enthusiasts.
Understanding Cadenzas
Definition and Historical Context
A cadenza is an elaborate, often improvisatory solo passage that occurs during a concerto, typically before the final orchestral reprise. Historically, cadenzas allowed soloists to showcase their virtuosity and interpretative skills. Traditionally, composers would leave the cadenza to the performer’s discretion, allowing room for personal expression. This practice began in the Baroque era and continued into the Classical, Romantic, and even modern periods.
Cadenzas in Viola Concertos
While the cadenza is more commonly associated with instruments such as the violin or piano, the viola has its own rich tradition of cadenzas. The unique timbre and range of the viola lend itself to expressive and intricate passagework, making cadenzas an essential part of the performance of viola concertos.
Cadenzas in Walton's Viola Concerto
Overview of Walton's Viola Concerto
William Walton composed his Viola Concerto in 1929, commissioned by the renowned violist Lionel Tertis. The concerto is notable for its lyrical melodies and rich harmonic language, drawing on both English folk music and modernist influences. The work is structured in three movements:
1. Allegro moderato
2. Andante con moto
3. Allegro molto
The Role of the Cadenza
In Walton's concerto, the cadenza occurs at the end of the first movement. This moment is pivotal, as it transitions from the orchestral dialogue into a personal statement from the soloist. The cadenza serves to highlight the emotional depth and technical prowess of the violist.
Characteristics of the Cadenza
The cadenza in Walton's work is characterized by several elements:
- Lyrical Melodies: The violist can explore the lyrical potential of the instrument, often incorporating elements from the main themes of the concerto.
- Technical Challenges: The cadenza often includes rapid scales, double stops, and intricate fingerings that test the limits of the performer’s technique.
- Emotional Range: Walton’s cadenza allows for a wide emotional range, from introspective and melancholic to exuberant and triumphant, showcasing the violist's interpretative skills.
Performance Considerations
When performing the cadenza in Walton’s Viola Concerto, musicians should consider the following:
- Personal Interpretation: Given the improvisatory nature of cadenzas, performers are encouraged to infuse their own interpretations.
- Connection with the Orchestra: Although the cadenza is a solo passage, maintaining a connection with the orchestral material can enhance the overall performance.
- Technical Proficiency: Mastery of the technical challenges presented in the cadenza is essential for a successful performance.
Cadenzas in Bartók's Viola Concerto
Overview of Bartók's Viola Concerto
Béla Bartók’s Viola Concerto, composed in 1945, stands as one of the most significant contributions to the viola repertoire. The work was left unfinished at Bartók’s death and was later completed by his student, Tibor Serly. The concerto is structured in three movements:
1. Allegro
2. Lento
3. Allegro
The Role of the Cadenza
In Bartók's Viola Concerto, the cadenza appears in the second movement, providing a moment of introspection and contrast to the more vigorous outer movements. This cadenza is crucial in establishing the emotional landscape of the work.
Characteristics of the Cadenza
The cadenza in Bartók's concerto differs significantly from Walton’s. Some defining characteristics include:
- Complex Rhythmic Structures: Bartók often employs irregular rhythms and syncopation, challenging the performer to navigate intricate patterns.
- Use of Folk Elements: The cadenza incorporates folk-inspired motifs, reflecting Bartók's interest in ethnomusicology.
- Contrapuntal Textures: The cadenza may feature counterpoint, allowing the violist to engage in a dialogue with themselves, creating a rich tapestry of sound.
Performance Considerations
Performing the cadenza in Bartók’s Viola Concerto requires careful attention to:
- Rhythmic Precision: Mastery of complex rhythms is vital for conveying the work’s character.
- Incorporation of Folk Elements: Understanding the folk influences can help the performer bring authenticity to the cadenza.
- Emotional Depth: The performer must balance technical execution with emotional expression, ensuring the cadenza resonates with the listener.

- Emotional Expression: Each cadenza serves as a platform for profound emotional expression, connecting the performer directly with the audience.
- Technical Challenges: Both require a high level of technical proficiency, pushing the boundaries of what the viola can achieve.
