How to play One by U2 on the acoustic guitar. This version is adapted for beginner players. The strumming pattern will take the most concentrated effort. Make sure you can play it in your sleep, before attempting any singing.  Don’t forget that the ghost strums are just as important as the actual strums when you’re first learning the pattern. There are four chords, Am, C, Fmaj7 and G. These are all relatively easy to change between if you use my finger suggestions.
