The speed at which the consumer moves in the store can be influenced by the tempo of the instrumental background music. Movements are clearly slower when a low tempo is played (72 BPM) and faster when music with a higher tempo is used (>= 92 BPM). This research links an increase in sales to a selection of music with a slow tempo, while the sales are lower when music with a high tempo is used. When consumers move through the store at a slower pace, they show an increased intention to buy.
