Square One by Jessie J is played in the key of C#m. Originally recorded in the sounding key of C#m, 'Square One' by Jessie J is best approached with a Capo placed on Fret 4, enabling guitarists to execute friendly Am shapes while fully preserving the studio pitch. The F#m chord can be navigated using an open F#m7 variation or capo shifting to exploit natural Em open fingerings across all primary song verses. The primary progression challenge lies in switching between C#m and E: keep your fingers hovering close to the fretboard rather than flying off between changes. Set your metronome at an initial practice tempo of 79 BPM in 4/4 time to master the '↓ - ↓ ↑ - ↑ ↓ ↑' strumming groove, emphasizing steady downstrokes on beats one and three before accelerating toward the studio speed of 110 BPM.
