Easy piano arrangement in the key of Ab at 128 BPM. Difficulty: medium. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a great workout for keeping your left hand anchored while your right hand drives the melody forward — the pedal bass pattern means your left hand will mostly sit on low Ab and Eb, giving you a steady foundation, but that repetition can lull you into autopilot, so stay intentional about keeping it rhythmically even at 128 BPM.

Your biggest challenge will be the Ebsus4 and Ebpow voicings mixed in with standard Eb chords; they're close in shape but easy to fumble if you're not anticipating the switch, so isolate those transitions and loop them slowly until your fingers know the difference by feel.

Start hands-separate at around 90 BPM, locking in the left-hand pedal tone groove before layering the right hand on top.

Once combined, nudge the tempo up in small increments — rushing is the number-one stumbling point here because the pop-upbeat energy tempts you to push ahead of the beat.

Stay patient with that, and this piece will genuinely solidify your confidence moving between major, minor, and suspended chords in a flat key, which opens up a huge chunk of the pop repertoire for you.
