Before the age of five, Henriette played piano with her grandmother. Renié was inspired to learn the harp after she heard her father perform a concert in Nice featuring Alphonse Hasselmans, a prominent harpist. She became inspired by the music and she decided that she wanted to play the harp under the instruction of Hasselmans. She began playing when she was eight, but she was still too short to reach the harp's pedals, so her father invented extended foot pedals to assist her.
