In today's guitar lesson I'm going to show you how to play Sia's epic cover of "California Dreamin'" originally by The Mamas and The Papas. It's fairly easy to play except for the one barre chord, B major, that finishes almost every phrase in this song. This will be a good song to practice that chord for sure! Watch the video above to learn the guitar parts and then use the chord chart below to sing and play along. Have fun!
