Happy belated birthday, Edvard Grieg! I missed it, but what’s a day when you’re celebrating your 170th, right? The story goes that Grieg wrote this after attending a performance of Macbeth. It includes an Intermezzo section subtitled Spirits of the Night, I use the una corda pedal during the rumbling arpeggios, but let up when the triplet chords begin. Overall, be careful not to rush the easy parts!
