Oh, man. I love a good printable! They're great for kids (we use them on road trips all the time), and I enjoy creating free downloads to share here on the blog, though I've mostly focused on creating printables for kids. But these Get to Know Your Ukulele printables are handy for all beginning ukulele players— kids and grown-ups alike.
Any musician needs to know her/his instrument, so I've included two versions of a ukulele diagram. The chart on the left is a variation of what's included in lesson one of my beginner's course, and all of the parts are labeled. The chart on the right makes an activity page out of it (I was inspired by my first grader's homework!).
