Memory systems include: episodic, procedural, semantic memory, classical conditions, priming and non-associative learning (Henke, 2010). All memory systems are independent of each other and are controlled by different regions of the brain (Henke, 2010). It is very likely that memory systems did not evolve with the purpose of memorizing everything (Nairne, 2010). If all the information presented were archived, storage problems could occur (Nairne, 2010). To avoid this, memory selectivity is required, and memory systems can respond to specific fitness-related information they receive due to the built-in biases of various memory types (Nairne, 2010). This literature review will focus on studying the mechanism underlying procedural memory and examining the effects of music on humans
