Note that music is ''not'' limited to such sounds that a human being might produce by fashioning an instrument for the making of a simplified or otherwise organized sound and then "playing" said instrument. The chirping of birds and certain insects may properly be called music, especially if the sound produced is particularly pleasant to the listener. Furthermore, some of the most sophisticated music attempts to imitate the sounds made by birds, insects, and other animals.

=== Notes, intervals, and scales ===

Two tones played together form an ''interval''. The simplest of all intervals is the ''octave'', formed by two tones, one of whose frequencies is the exact double of the other. The full collection of tones that one can play between the two notes of an octave is called a ''scale.'' In Western music, most scales are ''semi-tonal'', with twelve tones between the octave notes. (The high end of the octave is considered a repetition of the low end, but at twice the frequency.) [[Oriental]] music commonly has ''quarter-tonal'' scales, with twenty-four separate tones within an octave. Quarter tones are often difficult to distinguish for a Western listener, and such music, as a result, tends to suggest the sinuous movement of a snake.

The [[Greece|Greeks]] recognized early that fundamental tones in music have a simple and strict [[mathematics|mathematical]] relationship. As mentioned, the octave consists of two notes, one at double the frequency of the other. At ''triple'' the frequency, one hears a low fundamental tone, and a higher tone that is past the octave but roughly midway toward the second octave. If one then divides the high-tone frequency by two, one creates the interval called the ''perfect fifth'' or ''dominant'' interval, one of the most common intervals used in Western music. One can test this relationship by striking a note on a [[piano]] while holding down another key that is one octave higher than the perfect fifth. The second note will sound in sympathy with the first--because it is resonating with the overtone from the first note.

Music has a very powerful effect on the emotions of the listener. Music relies on [[sound]], and if "faith comes through hearing," then so does emotion. Music can instantly bring joy or sorrow, ecstasy or despair, and far more quickly than can any other form of art. Many musical composers insist that their music merely expresses emotions. This does not do music justice. Music does more than express emotions; it induces them.<ref>[http://www.musica.uci.edu/mrn/V3I1S96.html MuSICA Notes III(1), Spring 1996]</ref>

The amateur botanist Dorothy L. Retallack, in [[1973]], claimed to have found that music can have an effect on plants. "Positive" music (that produces joy or contentment) supposedly made plants flourish and even "reach" for, or grow toward, such music. Negative music (that produces frustration, restlessness, or especially anger and rage) supposedly caused plants to "recoil" (grow away) from the music, and prolonged or repeated exposure debilitates and eventually killed plants, or so she said.<ref>Retallack, Dorothy L.

No botanist has ever reproduced Retallack's claimed results. But the effects on animals and humans are far better documented and much more profound than any effect on plants that Retallack ever claimed. That animals, and especially [[dog]]s and [[cat]]s, recoil in horror from the sound of a poorly trained voice, is proverbial (and in fact the animals might be reacting to a sound that is not merely grating but acutely and physically painful to their ears). The Dovesong Foundation has found evidence for musical preferences by cattle<ref>[http://www.dovesong.com/positive_music/archives/basement/Cows%20and%20Classical%20Music.asp Cows Prefer Classical Music]</ref> and cetaceans.<ref>[http://www.dovesong.com/positive_music/archives/basement/Steinhart_Dolphins.asp Dolphins Don't Like Rock] (The article refers to the classic [[dolphin]] (family [[Cetacea]]), aka "porpoise," not the fish of that name.)</ref>

Commercial enterprises always attempt, at great expense of time, money, and effort, to find and deploy forms of music that will enhance worker productivity or cause prospective customers to behave in a manner calculated to make them purchase their goods and/or services. The pop selections played in supermarkets are a prime example.

Music has always been an adjunct to [[theater]]. This is especially true of the performing arts called ''opera'' and ''ballet'', but applies also to the use of music as an adjunct to a theatrical production, whether on the stage, as a [[motion picture]], or as a [[television]] show.

Music also has an obvious use in [[propaganda]], in which the propagandist seeks to manipulate people's emotions and stir them typically to rage and hostility against certain groups.
