For anyone interested, I just learned how to play the song Lava with the help of a Youtuber named Cynthia Lin.
I made a ukele music sheet with the chords and words and did my best to time the right word to the chords.
Here's a link to the sheet.

And here's a picture of the music sheet.

Click on her video and read the music sheet while listening and following Cynthia's pace.
Good luck and happy strumming :)
