How tempo, volume, and genre measurably change customer behavior, dwell time, spend, perceived quality, even staff performance. This is the research behind why curation isn't a nice-to-have.
Tempo is the single strongest lever in commercial music psychology. Slow tempo slows the pace of eating, drinking, and browsing, extending time in the space. Fast tempo accelerates behavior, useful for turning tables quickly but reducing per-visit spend.

Sales lift with slow-tempo vs fast-tempo music in restaurant settings, driven by longer dwell time and higher per-cover spend.

2. Volume and spending
Volume operates on a curve, not a line. Too quiet and a space feels empty or awkward for conversation; too loud and it drives people out or shortens visits. Most commercial spaces land best in a moderate 65–75 dB range, loud enough to establish energy, quiet enough to allow comfortable conversation.

The sweet spot for most hospitality and retail environments, loud enough to set energy, quiet enough for comfortable conversation.
3. Genre and brand congruence
Genre congruence, matching music to a product's cultural or brand identity, is one of the most reliable effects in the literature. North, Hargreaves, and McKendrick (1999) found that French accordion music alongside French wines, or German beer-hall music alongside German wines, doubled sales of the congruent product, with customers reporting no awareness of the music's influence when asked why they chose it.

4. Music and perceived quality
Congruent, on-brand music raises perceived quality of the product and service independent of what's actually being delivered, the same coffee tastes better, the same service feels more attentive, when the soundtrack matches the environment's identity.
+32%
Perceived quality increase reported for identical products/services when background music was rated as brand-congruent.
5. Music and staff performance
Music affects the people working in the space too. The right tempo and energy support pace and mood without becoming a distraction; the wrong music (too loud, too jarring, or on repeat all day) measurably increases reported staff fatigue and lowers service quality over a shift.
6. Practical implications for businesses
Match tempo to the behavior you want: slow for dwell time and spend, fast for throughput.
Keep volume in the 65–75 dB conversational range for most hospitality and retail contexts.
Choose genre for brand congruence first, personal taste second.
Refresh scenes regularly, repetition fatigues both customers and staff.
