Easy piano arrangement in the key of Bb at 82 BPM. Difficulty: easy. Color-coded notes — no sheet-reading skill required.

Teacher’s notes

This arrangement is a great way to build confidence with an oompah bass pattern — your left hand plays a low root note followed by a higher chord chunk, rocking back and forth steadily at 82 BPM.

Start hands-separate and get that left-hand pulse feeling automatic before you layer in the right-hand melody.

Most of your chords sit comfortably in B♭ major, but watch the A major chord — it's the one outsider in the set and often catches beginners off guard because your fingers need to briefly leave home-key shapes.

The move from B♭ to B♭maj7 is just one note shifting, so lean into that small color change rather than rushing past it.

Use gentle sustain pedal, changing it with each new chord to keep the ballad warm without blurring.

If any transition feels bumpy, loop just that two-chord switch slowly until it's smooth.

This is the piece that'll make oompah bass feel like second nature.
