Dwell is the metric your music moves first.
You have run the layout, the signage, and the staffing to hold people on the floor a little longer. The one input that changes how long a person stays, you left on shuffle. Here is what it is doing to your dwell numbers right now.
Of every number on a retail scorecard, dwell is the one music touches most directly. Basket and conversion are a step or two downstream. Dwell is immediate. The pace a person walks at and the length of time they are willing to stay both bend to two settings you are almost certainly leaving on default, the tempo and the volume of whatever is playing. Most chains have spent years working every other way to keep people on the floor longer and have never once treated the music as part of that job. It is the dwell lever sitting in plain sight that nobody in the chain has reached for.
The mechanism is old, and it is plain, older than most of the people reading this. In 1966 a study found that turning music louder pushed people toward the exit faster, and it did so without lowering what they spent. Volume sets pace. Ronald Milliman put numbers on the other side of it in a supermarket in 1982: slow music slowed shoppers by about nineteen seconds an aisle, and over a day that added up to a bigger basket. A restaurant running slow tempo kept diners at the table roughly eleven minutes longer, which turned into about three more drinks a table and close to 40 percent more bar revenue, with the food bill flat. Slow it down and people linger. Speed it up and they head for the door. The effect is real and it is old.
Where the easy version of this falls apart
Here is the part a vendor will not put on the slide. The Milliman result held in one supermarket on a particular day. In 2025 a team ran the same question across 140 stores against real transactions, and the overall tempo effect came back at zero. So if you walk away thinking the move is to drop a slow playlist into every store and watch dwell climb, you will be disappointed, and you should be. Slow music only moves dwell when the conditions around it line up, and getting those conditions right is the whole of the work.
Which dwell you are actually counting
The honest read goes one step further, and it is the step that matters most to anyone who owns the outcome. Comfortable dwell is a person slowing down because the floor is easy to be in, and they have a reason to stay. That dwell converts. The other kind is someone stuck, lost, waiting, circling with nothing pulling them forward, and a dwell report counts both the same. The receipt does not. Music that fits the person in front of it lengthens the comfortable kind. Aimed wrong, longer dwell is a person you have trapped, and they leave knowing it.
What actually decides whether the lever moves
What the music should do in your store depends on who is on the floor and when. The right pace at eleven in the morning, with a quiet store and an unhurried shopper, is not the right pace at six at night with a line building. It depends on the brand the music is sitting inside and on how crowded the room is at the moment. There is no single tempo to set and forget, which is exactly what the 140-store study proved. This is where a music behaviorist earns their keep, reading what your customers came in to do, fitting the music to that pace, and running it against a matched control so you can tell real dwell from a number that only looks like it. Without a control you are guessing, and dwell is too easy a number to fool yourself with. The full read on the research sits up in the field guide on store music and customer behavior, where the dwell and basket findings are laid out in order.
So pull the dwell figures for your stores, then pull up what is playing across them right now, and ask one question. Is that music holding people because they want to be there, or is it just noise in the room while your layout does the work alone. Right now, in most stores, nobody in the chain can answer that, because nobody chose the music against the number it moves.
