By the middle of XX century in the U.S., using surveys found that consumers are more pleasant to shop where some lighthearted melody is playing. Since then, music unobtrusively sucks money out of you. If the tempo of the music is fast, the customer spends less time in the store, as if adjusting to the tune, but he spends more money than he planned. Music creates an atmosphere of haste - the customer quickly grabs goods and goes to the checkout. This music is often played during sales in the mass market. Small prices, crowds of people and energetic music turns the head of fashionistas and fashionistas. Slow music also helps to increase sales, but it works where the goods are more expensive: stores of cosmetics and perfumes, porcelain dishes, Italian textiles, fine alcohol. This kind of music puts people in a trance, immersing them in dreams of a rich life, just like on TV.
