Gertrud Elisabeth Mara studied under Johann Adam Hiller in Leipzig for six years between 1765 and 1771. During this period, Hiller provided her with comprehensive musical training, including singing, piano playing, writing, and dance. This education played a significant role in shaping her development as an operatic soprano and contributed to the refinement of her dramatic vocal style.
The relationship between Mara and Hiller was that of a dedicated student and an established musical pedagogue, with Hiller known for leading a prominent singing school in Leipzig. His guidance helped Mara transition from her early career as a violinist to becoming one of the notable opera singers of her time. Their connection is remembered as an important chapter in both of their musical biographies.
