Musical form

In music, form refers to the structure of a musical composition or performance. In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments (as in the order of solos in a jazz or bluegrass performance), or the way a symphonic piece is orchestrated", among other factors.[1] It is, "the ways in which a composition is shaped to create a meaningful musical experience for the listener."[2]

Form refers to the largest shape of the composition. Form in music is the result of the interaction of the four structural elements described above [sound, harmony, melody, rhythm]."[3]

These organizational elements may be broken into smaller units called phrases, which express a musical idea but lack sufficient weight to stand alone.[4] Musical form unfolds over time through the expansion and development of these ideas. In tonal harmony, form is articulated primarily through cadences, phrases, and periods.[2] "Form refers to the larger shape of the composition. Form in music is the result of the interaction of the four structural elements," of sound, harmony, melody, and rhythm.[3]

Compositions that do not follow a fixed structure and rely more on improvisation are considered free-form. A fantasia is an example of this.[5] Composer Debussy in 1907 wrote that, "I am more and more convinced that music is not, in essence, a thing that can be cast into a traditional and fixed form. It is made up of colors and rhythms."[6]
