Переведите текст: a recent report by a british psychologist shows that practice is the key to musical success. nine out of ten people don't play a musical instrument because they think they aren't musical. however, professor sloboda believes we can all be good musicians. you need a support and help from your family, a kind teacher and lots of practice. professor sloboda thinks practice makes the difference betweenyoung people who are good at music and those who aren't. professor sloboda spoke to 120 children in school. they all played musical instruments. the good musicians practised three to four times more than the others. in fact, the best musicians practise 5 000 to 10 000 hours before they are 18. and yes - even mozart had to practise!
