After just a few months of studying with Hennebains, Moyse made swift progress with him and was invited to audit Paul Taffanel's class at the Paris Conservatoire. Taffanel was looked upon highly and although by the time Moyse had him as a teacher, Taffanel was sixty and retired from playing, Moyse's time with Taffanel was invaluable. Moyse immediately grasped the standard repertoire required for admittance into the Conservatoire. Under the guidance of Hennebains and with the approval of Taffanel, Moyse auditioned for and won a place in the flute class at the Paris Conservatoire in the fall of 1905. In 1906 with only one year of Conservatoire training, Moyse performed the newly written exam piece, "Nocturne et Allegro scherzando" by Philippe Gaubert. If Moyse was nervous, he did not betray it in his performance, with the stretching melody of the nocturne and the skipping, whimsical turns of the scherzo were perfect vehicles for his expressive tone and nimble technique. At the age of seventeen, Moyse accepted a first prize and was deemed ready for a professional career.
