This is an interactive online piano tutorial for Katy Perry's new track featuring Nicki Minaj "Swish Swish".
It's in the key of F minor, with a syncopated bass line. It uses diatonic jazz chords during the verse and pre-chorus.
In this tutorial, the left hand plays the chords while the right hand outlines the melody. You can turn off either hand in Practice mode to learn them separately.
