This beautiful song from Ed Sheeran is a really cool one to learn as it includes some really beautiful arpeggio ideas, alongside some pretty easy to play open chords to strum along with. It's Ed Sheeran at his best, and Simone walks us through it!
The opening picking part is really cool, and basically uses two chord shape ideas that it switches between using a fingerpicking pattern. I think it is easiest to consider two main chord shapes with your fingers when picking through this as shown in the fretboard below: (they are both essentially E major with melody notes)
For the rest of the song we are using 4 chord shapes, including some barre chord shapes. The chords are as follows:
For the groove we are playing the all downstrokes with palm muting. You basically play one chord per bar and you continue that downstroke rhythm throughout to create the 'driving' effect.
