Secular music in the context of "Symphony No. 9 (Beethoven)"

A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions. Genre is to be distinguished from musical form and musical style, although in practice these terms are sometimes used interchangeably.

Music can be divided into genres in numerous ways, sometimes broadly and with polarity, e.g., popular music as opposed to art music or folk music, or, as another example, religious music and secular music. Often, however, classification draws on the proliferation of derivative subgenres, fusion genres, and microgenres that has started to accrue, e.g., screamo, country pop, and mumble rap, respectively. The artistic nature of music means that these classifications are often subjective and controversial, and some may overlap. As genres evolve, novel music is sometimes lumped into existing categories.

Medieval music encompasses the sacred and secular music of Western Europe during the Middle Ages, from approximately the 6th to 15th centuries. It is the first and longest major era of Western classical music and is followed by the Renaissance music; the two eras comprise what musicologists generally term as early music, preceding the common practice period. Following the traditional division of the Middle Ages, medieval music can be divided into Early (500–1000), High (1000–1300), and Late (1300–1400) medieval music.

Medieval music includes liturgical music used for the church, other sacred music, and secular or non-religious music. Much medieval music is purely vocal music, such as Gregorian chant. Other music used only instruments or both voices and instruments (typically with the instruments accompanying the voices).

Claudio Giovanni Antonio Monteverdi (baptized 15 May 1567 – 29 November 1643) was an Italian composer, choirmaster and string player. A composer of both secular and sacred music, and a pioneer in the development of opera, he is considered a crucial transitional figure between the Renaissance and Baroque periods of music history.

Born in Cremona, where he undertook his first musical studies and compositions, Monteverdi developed his career first at the court of Mantua (c. 1590–1613) and then until his death in the Republic of Venice where he was maestro di cappella at the basilica of San Marco. His surviving letters give insight into the life of a professional musician in Italy of the period, including problems of income, patronage and politics.

Philippe de Vitry (31 October 1291 – 9 June 1361) was a French composer-poet, bishop and music theorist in the ars nova style of late medieval music. An accomplished, innovative, and influential composer, he was widely acknowledged as a leading musician of his day; the early Renaissance scholar Petrarch wrote a glowing tribute, calling him: "... the keenest and most ardent seeker of truth, so great a philosopher of our age." The important music treatise Ars nova notandi (1322) is usually attributed to Vitry.

It is thought that few of Vitry's compositions survive; though he wrote secular music, only his sacred works are extant.

Johannes de Grocheio (or Grocheo) (Ecclesiastical Latin: [jɔˈan.nɛs dɛ ɡrɔˈkɛj.jɔ]; c. 1255 – c. 1320) was a Parisian musical theorist of the early 14th century. His French name was Jean de Grouchy, but he is best known by his Latinized name. He was the author of the treatise Ars musicae ("The Art of Music") (c. 1300), which describes the functions of sacred and secular music in and around Paris during his lifetime.
