To learn Tess - Stupid chords, your practice should emphasize these chord progressions: D#m, B, F#, C#, D#m, F#, B, C# and F#. I suggest starting at a calm pace of 56 BPM, and as you gain confidence, approach the song's BPM of 112. With the song's key of F# Major, set your capo to fit your vocal range and chord choice.
