To jam and learn the simple chords for Classics Iv - Sunny chords, practice playing F#m, B, Em, G, C, F#m, Gm, C, Fm, G#, C#, Em and F#m in sequence. I suggest starting at a calm pace of 54 BPM, and as you gain confidence, approach the song's BPM of 108. Align the capo with your vocal depth and chord choice, bearing in mind the song's original key: A Major.
