This arrangement is a great way to build confidence moving between major and minor shapes in the key of G, and the octave bass pattern in your left hand will really strengthen your reach and timing at a steady 120 BPM.

Pay close attention to the Bm-to-Bm7 shift — it's subtle, just lifting one finger — but rushing it is the most common stumble I see, so isolate that transition slowly before speeding up.

Your right hand needs to stay relaxed through the C-to-Cmaj7 voice leading too; let that major seventh note ring naturally rather than punching it.

I'd suggest practicing hands separately for the first few run-throughs, locking in that left-hand octave pulse until it feels automatic, then layering the chords on top.

Once both hands are together, loop the verse section at around 90 BPM before pushing to full tempo.

The dramatic feel comes from steady, confident rhythm — not volume — so keep your dynamics controlled and let the chord colors do the emotional work.

This is the kind of song that truly cements smooth minor-to-major transitions you'll use constantly.
