Abstract
A computer application was written to complete the task of contour reduction. The application was used to complete analyses of twentieth-century post-tonal works for solo flute. The methodology of Rob Schultz’s Contour Reduction Algorithm was chosen for implementation. While contour reduction is a useful analytical tool, it is a meticulous and time-consuming process. Computer implementation of this procedure produces quick and accurate results while reducing analyst fatigue and human error. Java computer programming language is used to create a contour reduction application. This implementation greatly reduces the time needed to analyze a melody. Computer programming is combined with music analysis to produce informed and expressive musical interpretations.

It is worth noting that of the possible LCPs, these analyses contain predominantly LCPs \(<\)0 1\(>\), \(<\)0 2 1\(>\), \(<\)1 0 3 2\(>\), and \(<\)1 3 0 2\(>\). The nature of these LCPs only allows for one transformation, generally the retrograde, to be created from the prime. The exception is LCP \(<\)0 2 1\(>\), for which a prime, retrograde, inversion, and retrograde inversion can exist.

Change in predominant diachronic LCP demarcates formal divisions of the work. For space limitations, the discussion of form is limited here. See [1].

Segmentation of this work refers to the segmentation process developed by James Tenney and Larry Polansky, see [14].

Roger Graybill uses the term “gesture” to describe a grouping structure with a distinguishing internal dynamic shape [16].
