Let's start jamming Aimer - Ophelia chords, familiarize yourself with these chords - C#m, A, D, G#m, F#m, D, E and F#m in sequence. A good strategy is to initiate at 76 BPM and then accelerate to the track's regular speed of 152 BPM. To match your vocal range and chord inclination, adjust the capo in line with the key: A Major.
