You might be a bit taken aback if your tween daughter has been pleading with you to get a pink acoustic guitar. You probably associate guitars with moody teenage boys, not young girls who used to pretend to be princesses and play dress-up just a few years ago. You will probably think it best to buy an inexpensive guitar in case your little girl loses interest. However, before you let her give it up, you should try and encourage her to keep at it.
