Born to a father who was a helicopter pilot in the army and a mother who worked in animal control, Vianney comes from a family of three brothers.

[7] He grew up in Paris and studied at Notre-Dame-des-Oiseaux College in the 16th district, where he would write a song of the same name, present on his first album Idées blanches[8].

Finally, he studied styling at École supérieure des arts et techniques de la mode (ESMOD), graduating in June 2014.

It was Vaudey who encouraged Vianney to reveal his songs to the general public, and she arranged a meeting with vocalist Antoine Essertier, who offered to produce his debut album, Idées blanches, which was recorded throughout two weeks during summer of 2013 in the Auvergne mountains, not far from Vichy.

He took part in the 30-event tour of Florent Pagny entitled Vieillir Ensemble, and has recorded with other artists, including Samaha of Shaka Ponk, and then with Joyce Jonathan in "Les filles d'aujourd'hui".
