Teacher’s notes

This arrangement sits in the key of B at a relaxed 100 BPM, which gives you plenty of breathing room to focus on smooth chord transitions in your left hand — expect shapes built around B major, E, and F♯ that cycle in a steady, groovy pattern.

The real challenge here isn't speed but feel: Prince's rhythmic phrasing leans into subtle syncopation, so pay attention to where the melody notes land slightly ahead of or behind the beat in your right hand.

I'd suggest learning hands separately first, locking in that left-hand chord rhythm until it feels automatic, then layering the melody on top.

A common stumbling point is rushing through the verses because the note density looks simple — resist that urge and sit back in the groove instead.

Try looping the chorus transition a few times at around 70 BPM before bringing it up to tempo.

This is a fantastic song for training your hands to stay relaxed and independent, which is a skill that'll pay off in everything you play next.
