wewe can check on Youtube (or here) for some tutorials...They also give the notes in them. And I think it's a very easy way to learn!
But if wewe want to sheet music, you'll have to tafuta for yourself on Google au something. It's pretty easy to find. Just type the name of the song + artist and put sheet muziki behind it. It should give some results.
If kwa modern wewe mean upendo Story, White Horse, The Climb, This is Me and stuff I have the notes to them. Actually, I could igive wewe the website where to find them too :L
