Radiohead 的《15 Step》原曲为 Em 调。 Originally recorded in the sounding key of Em, '15 Step' by Radiohead is best approached with a Capo placed on Fret 2, enabling guitarists to execute friendly Dm shapes while fully preserving the studio pitch. To prevent hand fatigue on the challenging F barre chord, beginners can comfortably substitute an open Fmaj7 (xx3210) or small four-string F (xx3211) without sacrificing harmonic richness or vocal support. The pivotal chord transition occurs between Em and F: anchor your index finger as a pivot guide and keep your fingertips close to the frets to prevent hesitation on the downbeat. 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.
