Tonal Hierarchies in Jazz Improvisation
Statistical methods were used to investigate 18 bebop-styled jazz improvisations based on the so- called Rhythm Changes chord progression. The data were compared with results obtained by C. L. Krumhansl and her colleagues in empirical tests investigating the perceived stability of the tones in the chromatic scale in various contexts. Comparisons were also made with data on the statistical distribution of the 12 chromatic tones in actual European art music. It was found that the chorus- level hierarchies (measured over a whole chorus) are remarkably similar to the rating profiles obtained in empirical tests and to the relative frequencies of the tones in European art music. The chord- level …
Cross-cultural music cognition: cognitive methodology applied to North Sami yoiks
This article is a study of melodic expectancy in North Sami yoiks, a style of music quite distinct from Western tonal music. Three different approaches were taken. The first approach was a statistical style analysis of tones in a representative corpus of 18 yoiks. The analysis determined the relative frequencies of tone onsets and two- and three-tone transitions. It also identified style characteristics, such as pentatonic orientation, the presence of two reference pitches, the frequency of large consonant intervals, and a relatively large set of possible melodic continuations. The second approach was a behavioral experiment in which listeners made judgments about melodic continuations. Thr…
