Musical Form - More Recent Developments

More Recent Developments

A common idea is the depth of layers of form necessary for complexity, in which foregrounded detail events occur against a more structural background, as in Schenkerian analysis. Composer and music theorist Professor Fred Lerdahl, among others, argues that popular music lacks the structural complexity of multiple structural layers and thus lacks depth. However, Lerdahl's theories explicitly exclude associational details which are used to help articulate form in popular music; the theories of which are analyzed in music theorist and musicologist Allen Forte's book, The Structure of Atonal Music.

Western classical music is the apodigm of the extensional form of musical construction. Theme and variations, counterpoint, tonality (as used in classical composition) are all devices that build diachronically and synchronically outwards from basic musical atoms. The complex is created by combination of the simple, which remains discrete and unchanged in the complex unity...If those critics who maintain the greater complexity of classical music specified that they had in mind this extensional development, they would be quite correct...Rock however follows, like many non-European musics, the path of intensional development. In this mode of construction, the basic musical units (played/sung notes) are not combined through space and time as simple elements into complex structures. The simple entity is that constituted by the parameters of melody, harmony, and beat, while the complex is built up by modulation of the basic notes, and by inflexion of the basic beat. All existing genres and sub-types of the Afro-American tradition show various forms of combined intensional and extensional development. —Chester 1970, p.78-9

Similarly, Middleton maintains that "syntactic music" is centered on notation and "the hierarchic organization of quasilinguistic elements and their putting together (com-position) in line with systems of norms, expectations, surprises, tensions and resolutions. The resulting aesthetic is one of 'embodied meaning.'" on the other hand, non-notated music and performance "foreground process and are concerned with gesture, physical feel, the immediate moment, improvisation; the resulting aesthetic is one of 'engendered feeling' and is unsuited to the application of 'syntactic' criteria."

Connection and contrast may be achieved in new ways. Procedures of connection include: gradation, amalgamation, and dissolution. Procedures of contrast include: stratification, juxtaposition, and interpolation.

Especially recently, more segmented approaches have been taken through the use of stratification, superimposition, juxtaposition, interpolation, and other interruptions and simultaneities. Examples include the postmodern "block" technique used by composers such as John Zorn, where rather than organic development, one follows separate units in various combinations. These techniques may be used to create contrast to the point of disjointed chaotic textures, or, through repetition and return and transitional procedures such as dissolution, amalgamation, and gradation, may create connectedness and unity. Composers have also made more use of open forms such as produced by aleatoric devices and other chance procedures, improvisation, and some processes.
