Ten thousand hours is equivalent to roughly three hours a day, or 20 hours a week, of practice over 10 years... No one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.
Daniel LevitinIn order to be a world-class expert in anything, be it audiology, drama, music, art, gymnastics, whatever, one needs to have a minimum of 10,000 hours of practice. Unfortunately, it doesn't mean that if you put in 10,000 hours that you will become an expert, but there aren't any cases where someone has achieved world-class mastery without it! So the time spent at the activity is indeed the most important and influential factor.

Because the multiple-trace memory models assume that context is encoded along with memory traces, the music that you have listened to at various times of your life is cross-coded with the events of those times. That is, the music is linked to events of the time, and those events are linked to the music.
