Let's start jamming Martina Osorio Tiño - En La Oscuridad chords, familiarize yourself with these chords - C#, G# and C# in sequence. I suggest starting at a calm pace of 46 BPM, and as you gain confidence, approach the song's BPM of 92. Given the song's key of F# Major, adjust the capo to align with your vocal range and chord preference.
