Here you will find some of my favourite sites for songs, tuning, and tutorials on how to play the Ukulele
https://ukutuner.com/ – Has a great diagram depicting the tuning pegs and strings of the ukulele for tuning.
Click on each tuning peg to tune notes. Keep adjusting until the arrow points up in the center of the bright green area.
By far one of the BEST tutorials on youtube – Cynthia Lin goes step by step and has clear instructions for beginning to experienced players
James Hill is the Ukulele guru for all things Ukulele. Check out his youtube channel for tutorials, performances and more!
