Here's a quick video on reading and writing tablature for the ukulele. I believe that the best usage of tab is to take notes. There are plenty of places online where you can purchase tabs of your favorite songs, but IMHO it takes longer to memorize and execute to proficiency that way than to take your own notes while listening. Don't get me wrong, it's great to give you a guideline to follow, but be careful not to allow it to become a crutch. Again, these are my own opinions and philosophies; your opinions may vary. Aloha!
