A Model of Metric Coherence Anja Fleischer
2
Introduction Is it proper to assign a regular accent structure to the notes according to the bar lines?
3
RUBATO Describes the metric structure of the notes without considering the time signature and bar lines(outer meter). All onsets of notes which are equally distanced form an inner local meter.
4
metric analysis all inner local meters containing at least three onsets. a = {0, 2, 4, 6}. Only maximal local meters are considered within the analysis a0 = {0, 2, 4} is not considered.
6
upbeat of coherent character
8
Metric coherence Whenever a correspondence between inner and outer metric structure can be stated, metric coherence occurs.
9
The longest local meter m of length k = 31 choosing l = 31.

Metric weight W2,2 W2,3W2,3 W2,4W2,4 the greatest weights are located on the first beat of each measure

Listening experiments Credo-fugue from Bach’s B Minor Mess (46 persons) Outcome, a relationship was detected between metric coherence and the understanding of the corresponding interpretation by the listeners. Metric weights of higher degree of coherence led to a more convincing interpretation
