Waiting music: how audio accompaniment influences the perception of customer service

Music doesn’t just fill silence — it shapes how we experience time. When customers are placed on hold or spend time waiting in physical or digital environments, music becomes more than a background element. It creates emotional cues, adjusts perception, and affects how long the wait feels. The right kind of audio can turn frustration into patience, while the wrong kind can drive people away. Understanding how this works is key for any brand that wants to build trust and emotional consistency through sound.

Psychoacoustics of waiting: what goes on in the client’s head

The moment someone enters a waiting state, their brain switches into a different mode — more alert, more focused on the passage of time. In that state, sound has a direct line to how the experience is emotionally processed. According to psychoacoustics, our sense of time isn’t fixed; it is shaped by the sounds around us and our emotional response to them. If the music is irritating, time drags. If it’s engaging or calming, the same length of time feels shorter.

This makes waiting music more than just a decorative detail. It becomes a psychological tool for shaping perception. A few minutes of delay may feel smooth and intentional with the right soundtrack. But with the wrong sounds — too loud, too repetitive, or low in quality — it can feel like a breakdown in care. The music, often unnoticed on the surface, actually plays a key role in defining how the brand is remembered.

The influence of tempo, rhythm and tonality on the perception of time

Tempo plays a major role in the emotional pace of waiting. Slower tempos naturally lower the listener’s stress response, while faster ones can amplify it. But it’s not just about speed. The rhythm of a piece — how it pulses or flows — can create a sense of calm or activity. When paired with smooth transitions and tonal harmony, the effect is subtle but strong. A major key tends to evoke warmth and optimism, while a minor key often feels cooler or more introspective.

This is where tonality becomes essential. A relaxed, soft piano in a major key can guide the listener into a state of calm alertness, while dissonant or erratic melodies can have the opposite effect. Many brands use slow ambient music, gentle jazz, or nature-inspired sounds to suggest that the wait is temporary, but thoughtfully designed. The result is a sensory illusion — where time doesn’t stop, but it softens, and the listener feels more held than forgotten.

How brands use music as a mood management tool

Companies are increasingly treating music as a mood management device, especially during touchpoints that might otherwise feel cold or transactional. Waiting is one of those fragile moments when the customer feels temporarily disconnected. Good music bridges that gap and reintroduces emotion. Rather than just passing time, sound becomes a subtle way to create connection. It signals that the brand is still present, still attentive.

Some brands are now customizing their audio choices to match their broader identity. A luxury fashion label might use elegant string compositions to echo the sophistication of its image, while a wellness brand might choose soft chimes and textures that suggest balance and mindfulness. The goal is emotional coherence. Sound supports the same message the product, logo, or space is communicating. In some cases, companies even use advertising in ASMR format to create highly personalized audio touchpoints. In those situations, music becomes more than branding — it becomes a sensory expression of tone, care, and personality.

When silence is the best music: the strategic absence of sound

There are moments when silence works more powerfully than music. Intentional silence can express calm, focus, or seriousness better than any melody. It invites the listener inward, reduces sensory clutter, and can create a sense of emotional pause. But it has to be used thoughtfully. When silence is too complete or unexplained, it risks being mistaken for a technical issue or lack of care. It creates uncertainty, and people naturally fill that space with doubt.

Instead, small, quiet cues can be more effective. A brief ambient swell, a soft ping, or a minimal sonic gesture can let the listener know they’re not forgotten. Silence becomes a compositional tool, giving more meaning to the sounds that surround it. This approach is especially useful in app experiences or digital touchpoints, where long musical loops might be too heavy. Silence, when paired with minimalism and intention, can offer a sense of emotional space rather than emotional absence.

Different niches – different emphases: from banks to delivery

On-hold music should reflect the character of the brand and evoke the right emotions in the user. Different industries require different emphases — what works for one may be completely off-key for another.

• Banks: Use soft piano, smooth orchestration, or mellow guitar to convey a sense of reliability and care.
• Delivery Services: Prefer upbeat, rhythmic tracks that maintain high energy and suggest speed and movement.
• Healthcare Providers: Opt for neutral, slow, and calming sounds to reduce anxiety without veering into overly sentimental territory.
• Airlines: Blend modern and soothing elements to ease long wait times and emphasize professionalism.
• Tech Companies: Often go for minimalistic, ambient music that feels sleek, futuristic, and innovation-driven.
• Luxury Brands: Choose elegant, often classical or jazz-inspired tracks to communicate sophistication and exclusivity.

The key in every case is emotional alignment. Music isn’t just background noise — it becomes part of the user experience.

Why people drop calls: music as a point of loss of trust

People don’t hang up only because of long wait times. They disconnect when they start feeling like they’re no longer being cared for. Poor-quality music, distorted audio, or jarring transitions can break the fragile sense of presence. It’s not just unpleasant — it feels careless. And when sound feels careless, so does the company. A loop that repeats every 15 seconds without variation creates mental fatigue and gives the impression that no one is really there.

Trust is easily lost through sound. A tune that’s too upbeat can feel off-key when someone is calling with a complaint. A track that’s too emotional might feel manipulative. Sound must reflect emotional awareness, and many companies underestimate how quickly bad audio breaks rapport. People might not consciously say “the music made me hang up,” but that’s often exactly what happened. Brands that treat sound as part of the customer journey — not just as filler — have an edge in making those moments feel human.
