In many cultures, music is an important part of people's way of life, as it plays a key role in religious rituals, rite of passage ceremonies (e.g., graduation and marriage), social activities (e.g., dancing) and cultural activities ranging from amateur karaoke singing to playing in an amateur funk band or singing in a community choir. People may make music as a hobby, like a teen playing cello in a youth orchestra, or work as a professional musician or singer. The music industry includes the individuals who create new songs and musical pieces (such as songwriters and composers), individuals who perform music (which include orchestra, jazz band and rock band musicians, singers and conductors), individuals who record music (music producers and sound engineers), individuals who organize concert tours, and individuals who sell recordings, sheet music, and scores to customers.
The word derives from Greekμουσική (mousike; "art of the Muses"). In Greek mythology, the nine Muses were the goddesses who inspired literature, science, and the arts and who were the source of the knowledge embodied in the poetry, song-lyrics, and myths in the Greek culture. According to the Online Etymological Dictionary, the term "music" is derived from "mid-13c., musike, from Old Frenchmusique (12c.) and directly from Latinmusica "the art of music," also including poetry (also [the] source of Spanish música, Italian musica, Old High Germanmosica, German Musik, Dutch muziek, Danish musik)." This is derived from the "...Greek mousike (techne) "(art) of the Muses," from fem. of mousikos "pertaining to the Muses," from Mousa "Muse" (see muse (n.)). Modern spelling [dates] from [the] 1630s. In classical Greece, [the term "music" refers to] any art in which the Muses presided, but especially music and lyric poetry."
