Here's an acoustic guitar tutorial for how to play Cannonball by Damien Rice!
Damian Rice inspired countless artists (including Ed Sheeran) to learn guitar and write songs. Cannonball uses many classic acoustic guitar techniques that everyone should know - and not a barre chord in sight!
I advise learning the basic chords and strumming first. Then, learn the melody with single notes, the -try putting the two together to play the into on one guitar.

N.B. the variations on the main riff when Damian plays this song on one acoustic guitar, as opposed to the many layers of multi-tracked acoustic guitars on the official music video/ single version.

Damian strums this song mainly with his thumb. I found it sounded better for me to play with using the nail of the first finger to strum. Try both - see which you like!
