Griots vs. textbooks

Personally, I would prefer learning from textbooks rather than relying on storytelling when learning about history. Everyone knows stories told verbally always change. Even within an hour and a few high school kids one simple story can be dramatically altered from what it originally was. Now imagine if it were told thousands of times over hundreds of years. Certain aspects would obviously change. Also, stories told from a griot of a certain society could easily be slanted. Their kings may be told about as fair, powerful rulers but other societies may see them as ruthless tyrants. There are some benefits from storytelling and music based history. For one, it does make learning about it easier and more interesting. Also, it could be argued that the societies culture is more preserved through the art of music and dance. For me, I would like to stick to my boring textbooks and know the information I am getting is correct (hopefully). However, I respect the griots talent and dedication to their practice, so I do respect them and anyone who chooses to learn about history that way.
