The efficient approach to a sound background formation in retail plays an important role in consumer’s activity. Studies have shown that a well-chosen playlist, with reference to the time of day, increases an «average check». With few customers, mainly in the morning and afternoon, calm instrumental music both beautiful and neutral should be played. It creates a comfortable atmosphere, plunging into which the customer will want to stay in the store for a longer time. During rush hours, when the number of customers increases significantly, it is better to put rhythmic music to speed up the flow.
