Cheap Thrills

First off, it took me some time to choose the key of the harmonica to keep that melisma which starts the chorus with the words “Baby I don’t…”. I went with the 2nd position, B harmonica, and the key of F#m, where I have that bend on 3, which fits that phrase. If you choose this position you will have to play in 2nd position in minor and 11th position major, which can sound really soulful, because you can bend the strong chord tones (1, 3, 5) of both tonic chords in 2nd and 11th position. I also added the harmony for the line in the chorus “But I don’t need no money…”. And at the end, I used weaker steps over the F#m chord to add some spice: 2, b7, 4.

Tabs and the original song are below the video.
