Does classical music make you smarter?

On One Hand: Playing Enhances Learning.

Learning to play classical music increases spatial development when instruction begins early in life. The Clearing House on Elementary and Early Childhood Education states children learning to play classical music enjoy benefits of heightened spatial-temporal and arithmetic skills for up to two years after instruction ends.

On the Other: Listening Has Limited Benefits.

Listening to classical provides temporary benefits such as relaxation and enjoyment but no long-term developmental benefits. The Society for Quality Education states sensory skills will develop with or without listening to Mozart or other classical music.

Bottom Line

Listening to classical music produces temporary benefits, but researchers fail to determine long-term benefits. Learning to play classical music provides long-term benefits for children younger than 7 years old.
