A SONGChoose a song with lyrics you enjoy but don't have memorized. Listen to the song as many times as necessary to write down all the lyrics. Then learn to sing along. Once you've mastered one song, move on to another! Developing better habits of careful listening will help you in your understanding, thinking and remembering. Reconstructing the song requires close attentional focus and an active memory. When you focus, you release the neurotransmitter acetylcholine, a brain chemical that enables plasticity and vivifies memory.
