Her EMA performance wasn't set inside The SSE Hydro, like earlier sets in the night had been, instead she was broadcast from the nearby O2 Academy in Glasgow, which gave the performance an intimate feel.
The mom-to-be looked radiant in a fitted and sequined silver gown as she sat at her piano, hitting the keys and her notes perfectly in sync as always.
While she sang soulfully about the tragic global conflicts that dominate news headlines every day, the screen behind her was illuminated with images of extended arms, reaching out to each other as audience members raised protest signs of peace and harmony.
There was plenty of skin and gyrating in earlier performances throughout the show, but Keys ended things on a much more serene and thoughtful note, leaving everyone with something to think about.
