Orlando di Lasso (c. 1532 – 1594) was a composer of the late Renaissance. The chief representative of the mature polyphonic style in the Franco-Flemish school, Lassus stands with William Byrd, Giovanni Pierluigi da Palestrina, and Tomás Luis de Victoria as one of the leading composers of the later Renaissance. Immensely prolific, his music varies considerably in style and genres, which gave him unprecedented popularity throughout Europe. His name appears in many spellings, often changed depending on the place in which his music was being performed or published. In addition to Orlando di Lasso, variations include Orlande de Lassus, Roland de Lassus, Orlandus Lassus, Orlande de Lattre and Roland de Lattre.

Since these various spellings or translations of the same name have been known and accepted for centuries, and since there is no evidence that he stated a preference, none of them can be considered incorrect. Orlando de Lasso was born in Mons in the County of Hainaut, Habsburg Netherlands (modern-day Belgium). Information about his early years is scanty, although some uncorroborated stories have survived, the most famous of which is that he was kidnapped three times because of the singular beauty of his singing voice. At the age of twelve, he left the Low Countries with Ferrante Gonzaga and went to Mantua, Sicily, and later Milan (from 1547 to 1549). While in Milan, he made the acquaintance of the madrigalist Spirito l'Hoste da Reggio, a formative influence on his early musical style.

One of the most prolific, versatile, and universal composers of the late Renaissance, Lasso wrote over 2,000 works in all Latin, French, Italian and German vocal genres known in his time. These include 530 motets, 175 Italian madrigals and villanellas, 150 French chansons, and 90 German lieder. No strictly instrumental music by Lasso is known to survive, or ever to have existed: an interesting omission for a composer otherwise so wide-ranging and prolific, during an age when instrumental music was becoming an ever-more prominent means of expression, all over Europe. The German music publisher Adam Berg dedicated 5 volumes of his Patrocinium musicum (published from 1573–1580) to Lasso's music.
