This arrangement is a great workout for locking your hands into a driving, repetitive groove without losing focus.

Your left hand holds down a pedal bass pattern — essentially anchoring on one note while your right hand punches through a set of power chords and a couple of sus voicings like Bsus4 and Esus2.

Power chords are just root-and-fifth shapes, so the hand position stays compact, but at 122 BPM you need clean, snappy transitions — especially moving between Gpow, F#pow, and Epow in quick succession, where that half-step shift from G down to F# can trip you up if your fingers aren't already hovering.

Start hands-separate and slower, maybe around 90 BPM, and loop the main riff section until the chord changes feel automatic.

The most common stumble is rushing the sus chords because they feel unfamiliar next to all those power shapes — give them equal rhythmic weight.

Nail this one and you'll build real confidence keeping a steady, energetic pulse with minimal hand movement, which is the foundation of every rock-style keyboard part you'll play going forward.
