Esmeralda created and composed GrandMother; a contemporary a cappella choral piece that transforms the real memories and experiences of grandmothers into song. Continuing to this day, Esmeralda interviews grandmothers across the world and writes contemporary choral music inspired by their memories and personalities. The piece is written for an a cappella choir of women of all ages and is performed with the participating grandmothers on stage.

The project began in Florida and was developed during a three day residency at the Women of the World Festival 2018 at the Southbank Centre. The project continued when she was appointed as Associated Artist at the The Old Church, Stoke Newington, where she continued to compose and create a large community choir of over 60 female singers for a work- in-progress show and live recording. The project was performed at Union Chapel with all interviewed grandmothers present and also as a commissioned digital performance at Tedx Bath 2020, online.
