Ducu Bertzi is a Romanian folk musician. His songs are usually his own compositions, but he also has in his repertoire some Romanian folk songs.

He studied the violin for 8 years, and from the 9th grade he started the rock band "Mi bemol rock" with a couple of friends. With this band he would sing at high school parties and ball-rooms Romanian songs and songs from the repertoire of other band that were in fashion at that time.

The literature association from his hometown inspired him to follow the paths of poetry. Later, at the first poetry and folk music festival at Sighet, in 1973, he won the Grand Prize.

In 1976 he became part of the folk stage of "Cenaclul Flacǎra", and his first radio recording was made in 1979 for the song "Cînd s-o-mpărţit norocu" ("When luck was being distributed"). Since then, he has always been present on the national and European music stages, the number of his concerts only until 1996 being greater than 3200. Through his music, he tried to bring into the mainstream the poetry of not-so-well-known writers that he encountered and who impressed him, thus creating songs for their lyrics.

In parallel with his folk music career, he also revealed his talent on the theater stage, alongside his friend Florian Pittiş, and in a choir, under the guidance of master Ioan Luchian Mihalea.

His best-known songs are "Ṣi de-ar fi..." ("If it would be..."), "Floare de colţ" ("Edelweiss"),
"M-am îndrǎgostit numai de ea" ("I fell in love with her only"), "Suflet fǎrǎ chei" ("Keyless soul"), "Omul pǎdurii" ("Man of the woods").
