Teacher’s notes

This arrangement is a fantastic workout for smooth diatonic chord cycling in your left hand — you're moving through C, G, Am, F, and Em7 in block bass patterns, so focus on keeping those transitions even and unhurried at 74 BPM.

The Em7 shape is your sneaky challenge here; make sure your fingers settle into that added seventh cleanly rather than fumbling from the G chord before it.

Start hands-separate, locking in the left-hand chord changes until they feel automatic, then layer in the right-hand melody.

Watch for subtle syncopation in the vocal line — the melody often lands just off the beat, and rushing through those pushes is the most common stumbling point I see.

Loop the chorus slowly until the rhythmic feel sits in your body, then bring it up to tempo.

This is the piece that will truly solidify your I–V–vi–IV confidence under your fingers.
