Moe entered the Moltke Citizen School for girls, and it was here that her special musical abilities stimulated her musical participation. Moe often played at school party events and family gatherings, and began to compose at the age of 12. Eventually, she delved into larger compositions, such as an overture to the celebration of the 100th anniversary of Johanne Luise Heiberg's birth in 1913. She maintained contact with the school long after she was grown. At Moltke's funeral in 1928, she played his elegy on the Frederik church organ. She played at numerous charity events before, during and after World War II, and for many family celebrations. She wrote music for festive events in the Danish and Swedish royal families, such as a tribute march to King Gustav V of Sweden, and a wedding waltz to the heir to the throne, princess Margrethe of Denmark.
