Knockin’ On Heaven’s Door
This song is in the key of G major. If you were going to play a Pentatonic scale on the A string, would you start on your index finger or your pinky? What fret would you put that finger on?
G is on the 10th fret of the A string, and since we are playing in a major key, we would put our pinky on that note.
Here is the Pentatonic scale pattern starting on the A string:
For a different sound, you could also play a Diatonic G major scale with this song, starting on the same fret.
