This arrangement is a great way to get your hands comfortable with jazzy chord colors without being overwhelmed — the block bass pattern in your left hand keeps things grounded while your right hand carries the melody over some beautiful voicings like Gmaj7, Bm7, and Bbmaj7.

Pay close attention to the Bbmaj7 and Fdim transitions: those are outside the key of D, so your fingers won't fall into familiar positions automatically — slow those bars down to half tempo and loop them until the shapes feel natural.

At 116 BPM the rhythm is gentle enough to breathe, but you'll want to practice hands separately first so the left-hand chord changes don't pull focus from your melodic phrasing.

Use a light sustain pedal, lifting cleanly on each chord change to avoid muddying those rich extensions.

A common stumble is rushing through the Gm6-to-A7 move — give yourself the full beat there.

Once this clicks, you'll have real confidence moving between major seventh and minor seventh shapes, which opens up a huge number of jazz-standard and pop ballad arrangements for you going forward.
