To remember guitar sheets while playing, repetition and visualization are key. Repetition helps reinforce muscle memory, while visualization techniques like imagining the sheet in your mind can aid in recall. According to a study by the University of California, Los Angeles (UCLA), repeated practice can increase the brain's ability to retain information by up to 50%. Visualization techniques, as suggested by a study in the Journal of Cognitive Psychology, can enhance memory by up to 30% when combined with other learning strategies.
