This song by Adam Lambert is in G.
As I’ve repeated myself many times before, the fingers I used in playing all the videos are purely so that viewers can see the notes I played.
Please do not follow me in the use of fingers. In fact, it’s so much harder to do that!
Use the fingers you find most comfortable for playing the notes.
These are the “cheat” chords I played…
Part 1: G - Em - B7 - C
Part 2a: G - B7 - C
Part 2b: G - B7 - B7 - C
