In the quiet of the Copenhagen Metro, the clear, sweet notes of a flute panned across the train. As commuters looked on with smiles, the members of the Copenhagen Phil joined into a rendition of Morning Mood from Edvard Grieg’s Peer Gynt, Op. 23. As listeners drank in the beauty of the melody, perhaps they were aware that at least for this particular commute, they were bonded with the strangers on the train in their appreciation and joy. They boarded the train as many, but departed in unity as one.
