Using your First Act ukulele is a piece of cake. Just hold it in your lap or against your chest. Use your fingers or a pick to strum the nylon strings. To tune it, turn the guitar - style tuning gears until you get the right sound. When you're done playing, put it in a safe place away from extreme heat, cold, or moisture. Wipe the strings with a soft cloth after each use to keep them clean and sounding good. If you notice the strings are getting old or not sounding right, it's time to replace them.
