Correct Your Mistakes for best practice

Today I was playing my guitar and practicing a song I have almost memorized. One of the best techniques I have found to ensure the effective memorization of a piece is to always check the music as you are playing if you make any mistakes or even think you are playing it wrong. the reason I say this is that if you practice the section wrong, then you are very likely to remember it wrong when the time to play by memory comes around. Do not make that mistake. Always check your information to make sure you are learning the song the way it should be learned. Only when you really know it can you interpret it. Keep playing music.
