He is believed to be the first native of Quebec to devote his entire life to music An August 1844 article in the periodical Le Ménestrel described him as the "first national musician ". Born in Quebec City, Sauvageau was a largely self-taught musician, although he most likely received some instruction from Jean-Chrysostome Brauneis I for whose band he played in 1831-1832.
In 1833 he founded his own quadrille band, which he conducted until his death 16 years later.
He also conducted several other ensemles, including the Quebec Militia Artillery Band (1833–1836), the band of the Petit Séminaire (1841–1844), Musique Canadienne (beginning in 1842), the band for the Street Jean-Baptiste Society (from 1842), and the Quebec Philharmonic Union (1848-1849). Sauvageau was also active as an organizer of concerts and informal evenings of musical entertainment within his native city.
Many of these events featured performances by his private students, such as Joseph Lyonnais and Napoléon Aubin. The latter of whom became his brother-in-law.
Towards the end of his life, Sauvageau ran a music store.
He died in Quebec City at the age of 41.
