When Mashad Jalil was 12, his father Karbalayi Amiraslan died, then he started selling peas in the Shusha's square and therefore stopped his education.

Mashadi Jamil's son Fikret Amirov, Ganbar Huseynli, Telman Hajiyev and many others are graduates of this school.

Like many artists of the era, Mashadi Jamil learns the secrets of classical Azerbaijani mugham from the great musician Mir Mohsun Navvab.

While he was in Shusha and Ganja, he had successfully performed the roles of "Majnun", "Zayd", "Karam", "Rza bey" and others in the opera and operettas of Uzeyir Hajibeyov, and had conducted the theater orchestras.

After a long career in 1915, Mashadi Jamil wrote the opera "Seyfal-Mulk" and invited many artists to perform in Ganja.
