British psychologist Catriona Morrison states "Music is a powerful cue for storing and retrieving data ... you can use music to process new information more deeply. You can train yourself by associating what you want to remember - your new PIN for example - with a particular piece of music."
In her most recent project, Morrison uses the works of the Beatles to explore this music-memory link. She allows people to share the recollections sparked by the mention of particular album, song or band memory.
