Section Boundaries Experiment

The following excerpts have been marked with a "ding" sound for each section boundary. A section boundary may occur when salient changes in various musical aspects (such as harmony, timbre, texture, rhythm, or tempo) take place. Please listen to the excerpts carefully and rate the quality of the boundaries based on your own judgment.
