The earliest Greek music was associated with Greek [[theater]]. But beginning with the fall of Rome, music became largely liturgical. The primary influence remained the [[Roman Catholic Church]] until the twin movements of the Renaissance and the Reformation, each of which introduced a countervailing tradition.

From that time forward, most scholars divide music into "classical" music (composed primarily to achieve a high art) and "popular" music (composed for the masses and tending to achieve wide, but ephemeral, appeal).<ref>[http://www.thefreedictionary.com/popular%20music Popular music] defined at the Free Dictionary</ref> In the former category one can usually find music composed for these purposes:

# As an aid to worship, by placing the listener into a proper frame of mind for worship or instill in the listener a proper appreciation of the grandeur and glory of [[God]] and of the listener's own place in relation to Him.

"Classical music" tends to rely more on written notation, as a piece of classical music is generally held to transcend any particular interpretation of it.  In current practice, such music is performed in concerts where the audience is expected to remain respectfully silent and the performers dress formally; however, in the past such music was often performed at salons and other informal private gatherings. In addition, the increasing importance of the written transmission of such music has reduced the role of improvisation, which was extremely important through the beginning of the "Romantic" era.  Classical music also displays great musical complexity through the use of varied rhythms, chord progressions, counterpoint, and other compositional techniques, while maintaining a deep emotional content.

# To rally troops, either during training, on the march, or in battle.

# To celebrate military victory or the reign of a king, usually the one presently on the throne.

# Occasionally as a supplement to various forms of [[theater]]. Originally (especially in the Greek era) this meant the open-air live theater of classical fame. Today such music might accompany a live stage performance or several scenes in a [[motion picture]].

Popular music, on the other hand, is typically used:

"Popular music" on the other hand, tends to be more accessible to the general public through the use of simpler forms and relatively simple compositional techniques.  Much popular music is the product of modern business enterprise, as opposed to folk music (created by ordinary people for their own enjoyment) or classical music (which was originally written for religious practice or for the entertainment of the nobility).

# For entertainment, and more particularly for financial remuneration.

These two genres; however, are not necessarily distinct, as composers such as [[Bach]] and [[Mozart]] would often incorporate themes from "popular music" of their time into their works. Other classical composers like [[Ravel]] and [[Gershwin]] were well-known for their use of jazz idiom in works like the Piano Concerto in G major and "Rhapsody in Blue".  On the other hand, popular music has borrowed many themes from classical works (one notable example is "A Whiter Shade of Pale" by [[Procol Harum]]). In addition, "popular music" is not necessarily simpler than classical, as forms like jazz and progressive rock make use of complex time signatures that do not often occur in classical works, and some popular musicians like [[Frank Zappa]] are considered serious composers in their own right.

# As a powerful aid to [[propaganda]].

# Very frequently as a supplement to modern [[theater]] in all its forms, including stage, [[motion picture|motion pictures]], and especially [[television]].

# Rarely, to rally troops. One popular artist who achieved great distinction by winning acceptance of his music by military bands was [[Glenn Miller]].
