Boundary segmentation annotation dataset (Beethoven's WoO 80)

Boundary annotation dataset used in the article: "Science of music-based citizen science: How seeing influences hearing".Participants annotated segmentation boundaries of Ludwig van Beethoven's 32 variations on an Original Theme in C minor, WoO 80, as performed by Elaine Chew. The entire performance was divided into excerpts (theme and variations) and presented to participants in a shuffled order for a study of annotated music boundaries. Participants were randomly assigned one of seven combinations of auditory cues (hearing the music) and visual (piano roll, waveform, or both) cues for each track.The file contains items with the following key/value pairs:pieceID (string): identifier for the excerpt. For example "Beethoven_B32_2_Var_XXI"user (string): identifier for the group (G) and participant number. For example "INSEAD_G1-03"pieceNumber (integer): excerpt identifier from 0 to 32. For example 21time (float): Time in seconds from the start of the excerpt marking a boundary. For example 1.68strength (integer): Intensity or strength of the boundary from 1-4. For example 1dateCreated (timestamp): Time of creation of the boundary annotationlabel (string): Participant label (free text)<br>
