I tuned my guitar down a half step (Eb) to play this, so I’m actually playing in the key of Db. “With Us” is from the Hillsong Live ‘God Is Able’ album.
If you don’t know how to play these chords, watch my guitar lesson on chords in the key of D
Base pattern (use for most sections of the song):
D DU UDU, D DU UDU, …
During the instrumental section:
DuduDudu, DuduDudu, …
