Memorizing music can be challenging, but with the right preparation, can be effective and even fun. Noa Kageyama, Ph.D. highlights research from his article, "Wish You Could Memorize Better? Why a Little Bit of 'Verbalization' Might Be the Missing Ingredient" from Indiana University about how musicians can be more successful with memorization. Rote memorization or learning by repetition is most often practiced, but may not be enough for long-term learning and memorization. Indiana University discovered that written analysis or "verbalization" to identify patterns and structure in music plus rote learning offered a higher percentage of memory recall than "muscle memory" alone.
