This song isn't difficult in the slightest, but still fun on pro keys.
The song begins with you playing triads in a Bm-A-G-A pattern, but instead of playing the first A chord you play a slow trill.
The first verse and chorus are dominated by chords. But there are lots of kinds of chords! You've got yer major triads, minor triads, some minor sevenths, and a couple of diminished chords. And they all flow into each other really well.
The hardest part of the song comes after the first chorus, where you play a fast arpeggiated minor triad that took me totally by surprise on my first run of the song.
The second verse and chorus are shorter than the first but otherwise pretty much identical.
The song picks up with the sax solo that comes afterwards. It's all single notes, which should come as a relief given the chordfest nature of the rest of the song. The notes glide all over the keyboard and are just generally fun to play.
The ending of the song is the same as the choruses, but the chords are interspersed with some sweet sax licks from the solo. Super fun.
This is definitely the easiest and probably the weakest keys song in the H&O pack, but it's still worth picking up, whether you're a fan of the band or just looking for a chill but enjoyable keys chart.
