Easy piano arrangement in the key of D at 100 BPM. Difficulty: easy. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a great way to build confidence with Alberti bass — your left hand will roll through broken-chord patterns under each of the five chords (D, G, Bm, C, and Gmaj7), and at 100 BPM you have just enough time to land each shape cleanly without rushing.

The transition to watch is Bm to C: the roots are only a half step apart, but the chord shapes feel quite different under your fingers, so isolate that change and loop it slowly until it's automatic.

Start hands-separate — get the left-hand Alberti pattern steady like a heartbeat before adding the right-hand melody on top.

Once you combine hands, you may notice your rhythm wants to drag during the Gmaj7 sections; keep your internal pulse locked and count evenly.

A common stumble is tensing up on the upbeat hits in the melody, so stay relaxed through your wrists.

This is the piece that'll make Alberti bass feel like second nature — once it clicks here, it transfers everywhere.
