This arrangement sits in Ab major with four flats, so before anything else, get your hands comfortable on those black keys — let your fingers naturally settle into the Ab scale shape, because fighting it will slow you down all night.

Your left hand drives a steady oompah bass pattern, alternating a low root note with a mid-range chord hit, and at 80 BPM that's spacious enough to feel elegant but tight enough that sloppy timing will stick out, so practise the left hand alone with a metronome until it feels automatic.

Watch the Bdim7 and Fsus4 chords especially — they pop up as passing colors and the fingering can surprise you mid-phrase if you haven't mapped them out in advance.

The move from Fsus4 into F7 and then resolving to Bb is a moment worth looping ten times slowly; once it's in your muscle memory the whole B section will click.

Keep your pedal changes crisp on every bass note swap to avoid muddiness in that low Ab register.

Start hands-separate, nail the left-hand pattern, then layer the melodic right hand on top — the vocal-style melody needs to sing above everything, so voice it with a bit more weight in your pinky and ring finger on those top notes.

This is a fantastic piece for building confidence with richly chromatic chord progressions in a flat key, and once you own it, tunes in Db and Eb will feel far less intimidating.
