Have you ever had a song stuck in your head for what seems like days? The same words and melody looping over and over again? While it might be frustrating, your brain is actually doing some really amazing things as you recall Lady Gaga’s Bad Romance for the hundredth time that day. When a song gets stuck in your head it may have something to do with our involuntary memory, which encodes music in many different ways, helping us to remember a tune we’ve only heard once at our niece’s 11th birthday party. It’s a powerful concept; try applying this to an educational setting, and we can achieve considerable results.
