Let's start jamming Gertrudis - No Sé Si chords, familiarize yourself with these chords - F#m, A, B, F#m, A, E, B, A and F#m in sequence. A good strategy is to initiate at 55 BPM and then accelerate to the track's regular speed of 110 BPM. With the song's key of E Major, set your capo to fit your vocal range and chord choice.
