Where the quartet has played, and how often.
Memory care, senior residences, nursing centres, hospitals, a cancer centre, a veterans medical centre and one conference for the social workers who look after all of them.
Five plates, one axis — the same move as the timeline above.
A row that scrolls sideways, snapping plate to plate. All five sit in view on a desktop; on a phone one and a half do, and the next one peeks in to say the row continues.

First concert
Brightview Memory Care
Annandale, Virginia · November 17, 2023
Their first concert was at Brightview Memory Care in Annandale, Virginia. The residents’ faces lit up as music filled the room — smiles were everywhere. The quartet returned twice that same school year.
Micaela, Mina and Hyunseo joined the founding four. More players means more rooms, more repertoire, and concerts that can run when school schedules collide.
