Whether you're a lifelong musician or have never even played an instrument, music is an access key to your memory, your pre-frontal cortex.

Michael Thaut

When a musical memory is triggered in people with memory disorders, they don't just remember the song, they also usually remember some other autobiographical memories that are connected, they remember at least for a moment where they are and who they are. And that can lead to very good, important moments, sometimes very emotional scenes where there is a reconnect for a moment, a recognition.
