Easy piano arrangement in the key of E at 75 BPM. Difficulty: easy. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a great way to build confidence with a four-chord pop progression — you'll cycle through Em, G, C, and D at a gentle 75 BPM, which gives you plenty of breathing room to nail each transition.

Your left hand carries a walking bass line, so focus there first: practice it alone until the stepwise motion between chord roots feels automatic, especially the reach moving from C up to D, where beginners tend to rush.

Once that's steady, layer in your right hand chords — keep them light and even, since the dramatic mood comes from the bass movement, not from pounding the top.

Watch the shift from G to C closely; it's the spot most students stumble because both shapes sit close together and fingers want to blur them.

I'd suggest looping just those two bars at half tempo until the change is clean.

Use a little sustain pedal to connect the walking bass notes smoothly, lifting right on each new chord so things don't get muddy.

This is the piece that'll lock in your walking-bass coordination for good — once your hands feel independent here, you'll carry that skill into everything else you play.
