Empirical research on the perception of large scale structure provided support for a concatenationist approach, and several authors have suggested that architectonic account of musical structures expresses more the structure intended by composers than the structures perceived by listeners (Cook, 1987). Several studies have investigated the perception of global form by systematically manipulating the global organization of musical pieces (Gotlieb & Konecni, 1985; Tillmann & Bigand, 1996). All confirmed the weak sensitivity to global form. However, other studies (Deliège, 1989; Clarke & Krumhansl, 1990) showed sensitivity to large scale structure in contemporary music. Background in musicology The concatenationist view conflics with the traditionnal concepts of form as developped by music theorists (Schenker, 1935; Lerdahl & Jackendoff, 1983). Organicist and architectonic concepts describes hierarchical structures inside a musical phrase, between phrases of a musical piece, and between movements of a whole piece. Other musicologists, such as Stoïanova (1978), distinguishes the kinetic aspect of musical time and the static aspect. Kramer (1988) defends the idea that linearity and non-linearity are the two fundamental means by which the music structures time and time structures music. Aims The aim is to explore the sensitivity of participant to large scale structure, the perception of musical coherence and the effect of temporal context. Method 40 subjects participated in this experiment. Six musical pieces, half from contemporary music, half from actual popular music were segmented in 28 or 29 chunks of 6 seconds on average. In the scrambled version, the temporal order of these chunks was altered with the constraint that the transitions between two chunks never created acoustical. Participants were told that two sound ingeneers had been asked to organize the chunks in a musical coherent way. One of the ingeneers was an expert but not the other one. Two main tasks were required of our participants. First they were required to indicated “on line“ when they perceived an incoherent link. At the end of the piece, they indicated which of the two sound ingeneers they thought had worked on the piece. A control experiment consisted in presenting chunks two by two without the whole musical context. Participants were required to perform a similar task as the first task. Results The finding demonstrates a moderate sensitivity to large scale structure which was found for both popular and contemporary musical styles. Numerous errors were detected in the scrambled version. Musicians and nonmusicians found, in majority, that the scrambled pieces were due to the "novice engineer". The majority of the incoherences found were unprepared abrupt changes, unsolved melody implications, stopped dynamic processes, incongruous juxtapositions of segments, etc. In the control experiment, which replicates the task in a shorter temporal context (6 sec.), the increase in the number of false detections was surprisingly more massive in coherent than in incoherent versions. Conclusion This experiment shows the importance of the temporal context for the capacity to evaluate rhetorical coherence in music. The subjects seemed to need a temporal context much longer than 6 seconds especially in coherent versions. References Clarke, E. & Krumhansl, C. (1990).
