This arrangement is a great workout for driving, rhythmic confidence in your left hand — that oompah bass pattern needs to stay rock-steady at 140 BPM, so start slow (try 90–100 BPM) and lock in the bass-chord, bass-chord bounce before you add the right hand.

Your six chords sit nicely in B♭ major, but watch the move between B♭ and B♭sus2 — it's just lifting one finger, yet at tempo it's easy to rush and blur the two together, so isolate that switch until it feels automatic.

The Dm to C transition can also catch you off guard since it moves quickly and sits a little differently under the hand; loop those two bars until the fingering is second nature.

Once both hands are comfortable separately, bring them together at a reduced tempo and bump it up in small increments — don't chase full speed until the groove feels effortless.

Pedal sparingly here; too much sustain will muddy that punchy pop-rock energy, so keep it dry or use quick half-pedals at most.

This is the piece that'll really solidify your ability to hold a steady oompah groove under a melody — once you own that skill, a huge number of pop and rock songs will feel easier.
