Playing certain music while eating can improve the taste of food and drink, an Oxford University study has found.

According to Professor Charles Spence, listening to music can change the way you eat food by tricking the mind.

The study found that sour tastes were emphasised by high pitches while richer sounds could emphasise sweet tastes.

But Prof Spence said the perfect sound to improve saltiness has continued to elude him.

For the study, volunteers were given chocolate before listening to two different pieces of classical music to test their senses.

Prof Spence is now working with Krug to produce an app to match wines to music.
