Applause between movements in a classical concert is not a mistake but evidence of the most honest emotional response to the music; what matters more than rules is a genuine connection with the composition.

#. Hesitant Hands

There is an awkward moment in the audience of a classical concert. The music seemed to have ended. It was beautiful, and you wanted to clap. But no one else is clapping. You glance at the person next to you; they are sitting silently. You lower your two hands that were about to applaud. A moment later, the music begins again, and only then do you realize: it wasn't over yet. For someone unfamiliar with concerts, this moment is embarrassing. It’s because it’s hard to know when to clap. From a performer's perspective, the very fact that such embarrassment exists in the audience feels regrettable. This is especially true if it is my performance and the audience has come to celebrate my music.

 

#. The Reason for Silence and the Discomfort It Brings

Classical performances have an old unwritten rule. Most works are divided into several "movements" played in succession, and it is customary not to clap between these movements. Where did this custom come from? It is not a simple rule but one derived from the structure of the music. Each movement may sound like an independent part, but they are actually connected within one large flow. If applause breaks in before this flow is completely finished, the tension and lingering resonance created by the music are severed—much like the lights coming on just before a movie's climax. Therefore, waiting to clap is a sort of "device to protect concentration." It is a minimal agreement to maintain the atmosphere created by the performer and the audience until the very end. The problem is that this agreement is causing discomfort for modern audiences. For those unfamiliar with classical music, it isn't even clear what a movement is. There is no standard to judge where a section ends or if the piece is over. In that state, the moment they clap, pressure arises that they might be "wrong." As a result, the audience becomes conscious of the rules rather than immersing themselves in the music.

 

#. From Free Response to the Rule of Silence

In fact, classical music was not always this strict. Concerts before the 19th century were much more liberated. Audiences reacted naturally while the music was playing, and applause between movements was a matter of course. People cheered when they liked a passage and even requested encores for particularly moving movements. Mozart enjoyed these reactions and sometimes directly induced applause from the audience. For his Symphony No. 31, first performed in Paris in 1778, he pre-calculated parts where the audience would be enthusiastic and, when applause broke out during the performance, he reinserted that same passage at the end of the first movement to draw another round of applause.

 

#. Who Created the Rules?

When and why, then, did we start to refrain from clapping during performances? This change was not made in a single moment but formed gradually through the 19th century, with composers playing a significant role. Mendelssohn instructed certain works to be played without pause between movements or designed them with such structures. Notably, his Symphony No. 3 is formally composed of four movements, but it was written to be played as one continuous flow according to his intention. Later, Wagner viewed music not as simple entertainment but as a reverent experience requiring focus. He believed unnecessary applause or curtain calls during a performance could blur the impression of the work and even requested that people refrain from actions that broke the flow. Additionally, the score of Mahler's "Kindertotenlieder" includes a note stating that the five songs should be understood as an inseparable whole and that the flow should not be interrupted by applause. However, this sentence is closer to an explanation added during the publishing process rather than a direct instruction from the composer himself. These customs of refraining from applause between movements gradually became established as definitive rules.

 

#. Recording Finalized the Rule

Entering the 20th century, this trend was further solidified from a completely unexpected direction: the advent of recording technology. If applause broke in between movements during a live CD recording, it became mere "noise" rather than a matter of musical judgment. To ensure recording quality, audience reactions had to be controlled, and that necessity hardened into etiquette. In other words, this custom, which had gradually formed for musical reasons, was completely sealed by recording technology. The moment it became a matter of quality rather than just culture, it was no longer a choice but a rule.

 

#. Welcome the "Mistaken" Applause

Given these standards, we should reconsider the person involved. The person who tries to clap right after a movement ends because they were truly moved—is that person really listening to the music incorrectly? No. On the contrary, they are the ones reacting most honestly to the music. Wanting to clap when moved and wanting to make a sound when something is beautiful—that is the original human response to music. Just like the audiences of Mozart's era. Knowing the rules is different from knowing the music. There is no evidence that a person who has learned how to suppress applause listens to music better. Rather, the person who clapped with conviction was, in fact, the one closest to the music at that moment. There is no such thing as "wrong" applause.
