00:48 - Progressions
There are only 3 chords in the entire song. The difficult part is that they are all barre chords - F#m, G#m and A.
Each chord lasts for 2 beats forming a 2 bar pattern that repeats throughout the song.
2:07 - Rhythm and Feel
Call The Doctor employs a slow Bluesy swing feel.
3:22 - Harmonica
The song is in the key of F#m which is the relative minor to A Major so I have found that an A Major harmonica works well for this melody.
5:53 - Harmonica with Guitar
Run through the harmonica part with the guitar accompaniment.
6:35 - Full Song Play Along
Let's play through the whole song together.
That's it for Call The Doctor.
Stay In Tune. Peace.
