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

Teacher’s notes

This arrangement is a fantastic workout for navigating chromatic chord movement — you've got 14 chords here, and many of them (Ab, Bb, Db, Eb, Gb) sit outside the key of C, so your hands will be constantly shifting into unfamiliar shapes.

Start hands-separate at around 70 BPM: get your left hand comfortable with that oompah bass pattern first, because keeping it steady while your right hand handles the melody is half the battle.

Pay special attention to the transitions around Bbm and Cb — those are the spots where most students hesitate and lose the groove.

Loop any four-bar phrase that trips you up at least ten times before moving on.

Once both hands feel confident alone, combine them in short sections rather than trying to play straight through.

The syncopated R&B ballad feel at 100 BPM rewards a relaxed wrist, so stay loose and let the rhythm breathe.

This is the piece that'll genuinely build your confidence moving through chromatic harmony — a skill that unlocks so much of what makes soul music feel rich.
