This graphic visualization complements our dataset deposited on GitHub.
Each horizontal line below represents the timeline of an exposition section according to the order of appearance in the dataset, and is preceded by information regarding the containing work and movement. The number at the extreme left represents the first measure number of the exposition (typically, measure 1). The number on the extreme right represents the exposition's duration in measures.
The labels correspond to the four closure types discussed in our report, inspired by the punctuation system of Heinrich Christoph Koch (1782–1793). Timestamps (measure number, beat in subscript) indicate the beginning and end of a given closural event, where the beginning stands for the cadential arrival, and the end for the end of the postcadential space. In case the beginning and end coincide, the end timestamp is omitted. Elided cadences are marked with a small letter 'e' following the end timestamp.
Adapting Joseph Riepel's (1752–1768) convention of using black and white squares, we represent authentic cadences by a full square, and half cadences by an empty square. The squares are color-coded, where blue indicates the primary key, and red the secondary key (in major: V; in minor: III, or, in a single case, v). Insofar as our data allows to determine the exposition's tonal areas, the timeline itself is colored in a similar manner, leaving unidentified segments grey.
