A cadenza is a passage in which a soloist steps into the spotlight, usually while the orchestra falls silent. In a concerto, it often appears near the end of a movement and gives the player room to explore the music’s ideas with unusual freedom.
You can hear the change even if you know nothing about musical form. The steady exchange between soloist and orchestra stops. For a moment, one musician seems to be deciding where the music will go next.

What happens during a cadenza in a concerto?
A concerto brings a solo instrument into conversation with an orchestra. Sometimes the soloist leads; sometimes the orchestra answers, supports, or takes over. A cadenza changes that relationship: the orchestra pauses, and the soloist carries the musical argument alone.
In many concertos from Mozart’s and Beethoven’s time, this happens late in the first movement. The music reaches a point that feels ready for an ending, then holds back. The soloist may revisit themes you have already heard, race through rapid notes, or move between quiet reflection and display before the orchestra returns.
That pause is part of the effect. Without the orchestra’s regular pulse underneath, the soloist can stretch a phrase or take a surprising turn. The passage may sound spontaneous even when every note has been planned.
Cadenzas do not all last the same amount of time or follow the same pattern. Some are brief; others become substantial episodes. What joins them is the shift in attention: one player takes charge just when the larger ensemble seems poised to finish a thought.
Are cadenzas improvised or written down?
Originally, a cadenza could give a performer space to invent music during a performance. That possibility helps explain its distinctive sound. A soloist might decorate a melody, combine familiar themes, and build toward the orchestra’s return.
Today, a performer may play a cadenza written by the composer, one written by another musician, or one of their own. In some concertos, several established choices are available. So hearing two performances of the same work does not guarantee you will hear the same cadenza.
“Improvised” also needs a little care. It does not necessarily mean playing random notes or abandoning the piece. A convincing cadenza grows from the concerto around it: it can recall a theme, sharpen a contrast, or make an expected ending feel newly earned.
Likewise, a written cadenza need not sound stiff. A performer still shapes its timing, emphasis, and color. If you hear a passage that seems to pause, hesitate, and surge forward, that sense of freedom may come from both the notes and the way they are played.
Where does a cadenza happen? Four concertos to try
Start with the first movement of Mozart’s Piano Concerto No. 21, K. 467. Follow the exchanges between piano and orchestra, then notice the late moment when the piano is left on its own. The contrast makes the cadenza easier to recognize: the soloist’s freedom stands out because you have heard the two forces working together. For a different side of the same concerto, our guide to its Andante explores the lyrical middle movement.
In the first movement of Beethoven’s Violin Concerto, Op. 61, listen for the violin’s extended solo passage near the end. By then, the concerto has given you time to become familiar with its musical ideas. The cadenza lets the violin gather and reshape them before the orchestra completes the movement. If you compare recordings, pay attention to how much the chosen cadenzas differ.
The first movement of Brahms’s Violin Concerto, Op. 77 offers another useful comparison. A cadenza by violinist Joseph Joachim is often played, though performers have other options. Listen for how the violin’s solitary passage grows out of a movement in which soloist and orchestra have shared weighty material. Then try the concerto’s dance-filled finale to hear how differently a soloist can stand out while the orchestra remains involved.
Finally, try the first movement of Rachmaninoff’s Piano Concerto No. 4. Its piano writing is a reminder that a brilliant solo passage and a cadenza are not automatically the same thing. As you hear the piano take command, ask whether the orchestra has stopped, whether the passage interrupts an expected arrival, and how the larger musical flow resumes. Those questions are more useful than judging a passage by how fast its notes go.
You do not need to memorize the location of each example. On a first hearing, simply follow the balance of sound: orchestra and soloist together, then perhaps the soloist alone, then the full ensemble again. That change tells you more than a stopwatch could.
How to recognize the orchestra’s return
The end of a cadenza can be as revealing as its beginning. In many older concertos, the soloist builds toward a sustained trill, a rapid alternation between two neighboring notes. The orchestra then reenters and brings the movement toward its close.
Listen for the feeling of a sentence finally reaching its period. The soloist has delayed that ending, examined a few possibilities, and handed the music back. A returning orchestral theme may sound familiar, but its arrival can feel stronger because you have waited for it.
If you lose your place, focus on one simple question: Who is setting the pace right now? During much of a concerto, the soloist and orchestra negotiate it together. In a cadenza, the soloist can seem to hold time in their hands. When the orchestra comes back, you hear the shared pulse return.
That is why a cadenza can feel different even without the loudest or fastest playing in the movement. Its drama comes from a change in musical control. Once you know to expect that change, the pause before the orchestra returns becomes something to enjoy, rather than a mystery to solve.
Frequently Asked Questions
Is a cadenza always at the end of a concerto?
No. The familiar pattern places one near the end of a concerto’s first movement, but composers have used solo passages in other positions and forms. Listen for what the passage does in its particular piece rather than expecting a fixed address.
Is every flashy solo passage a cadenza?
No. A soloist can play difficult, brilliant music while the orchestra continues underneath. A cadenza typically gives the player a more independent stretch, often at a point where the music seems to pause before moving on.
Can two violinists play different cadenzas in the same concerto?
Yes. Performers may choose among cadenzas written by different musicians, depending on the work and its performance tradition. Comparing those choices can reveal how each violinist hears the concerto’s themes and its approaching conclusion.
