Roland de Lasso (1532~1594) was born in Mons in 1532 and died in Munich in 1594. He was in the choir as a child and studied music at the church of St. Nicolas. When he was 12 years old, he went to Sicily and later to Milan. This erratic life made it easy for Lasso to accept different styles. He also traveled to England and France. In 1556, he was summoned to the palace of Alba V (Albert V), and in 1560 he was promoted to captain of the court band, a position he held until his death.

The largest composer of the Flemish school (the main music school of the Renaissance), he paved the way for the transition from polyphonic music to tonic music. His works are almost all vocal music. ***There are more than 2,000 songs. Among them are masses. Motet . Hymns and secular musical compositions. Like an Italian pastoral. France's Chanson, Germany's Lieder, etc. Russo’s work is breezy and accessible. Full of human touch. The famous work "Poor Man" interweaves vocals with instrumental accompaniment. echo each other. It can be said to be the most wonderful song. Russo's works are very interesting in life. His humor and personality are often reflected in his lyrics. The lyrics in "I'm a poor man" goes like this; I'm a poor man. What did you do? Married a concubine. It would be nice if I didn't marry. You can certainly imagine our daily quarrels from the table to the bed. ’

His musical style is free, lively and expressive, with concise and powerful melody progression. Each part has its own independence, and does not necessarily follow the principle that the outer treble part is the main part. He attaches great importance to the meaning of lyrics. He once used the curve of the melody to express the image of clouds and valleys. Lasso never rejected the chromaticism of the time.
