Easy piano arrangement in the key of G at 120 BPM. Difficulty: beginner. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a great way to build confidence with a steady eighth-note right-hand pattern over simple chord shapes in the key of G.

You'll mostly be working with G, D, Em, and C — the classic I–V–vi–IV family — so your left hand will settle into a comfortable rotation once you memorize the shape shifts.

At 120 BPM the tempo feels brisk, so start at around 80 BPM and focus on making the transition from Em to C smooth; that's where most beginners hesitate because the hand has to shift position slightly.

Practice hands separately first, especially the left hand, until the chord changes feel automatic, then layer the right hand in.

Once you're comfortable, try looping just the chorus at full speed — it's the most repetitive section and will lock in your timing fastest.

Watch out for rushing during the pre-chorus; keep your rhythm even and resist the urge to speed up as the energy builds.

By the end of this piece, you'll have that I–V–vi–IV progression so deep in your muscle memory that dozens of other pop songs will feel instantly familiar under your fingers.
