Let's start jamming Iri - Aitaiwa chords, practice the chord sequence E, F#m, A, E, D, E, F#m, C#m and A. A good strategy is to initiate at 72 BPM and then accelerate to the track's regular speed of 144 BPM. Considering your vocal pitch and chord choices, adjust the capo in accordance with the key: A Major.
