     Scientists have discovered an interesting link between music and cheese. The creation of goodcheese involves a complex dance between milk and bacteria. A new study shows that playing the right tune   16        this dance unfolds changes the final product’s taste. A top Swiss cheese-maker and a team of researchers from Switzerland conducted a six-month test to look   17   the effect music had on thematuration process of Emmental cheese. After the cheese had matured, it was assessed by the researchersand a jury of   18    cheese experts. The researchers found that cheese that had been played hip-hop had astronger aroma and flavor than the other     19      . The cheese experts reached the same conclusion as theresearchers - the hip-hop cheese was the tastiest. One possible explanation is that humidity, temperature ornutrients are probably not the only things that   20     taste. Sounds, ultrasounds or music can also havephysical effects.
