Excerpt from a transcription of a trope to the antiphon Dominus Dixit with indicated structural elements. Trope elements have a numerical ID; primary chant cues are indicated by letters.

Figure 2
Degree distributions of manuscript nodes (top) and trope element nodes (bottom). A base‑10 logarithmic scale is used for both y‑axes. On average, a manuscript node contains around 112 trope elements, and a trope element is contained in around four manuscripts.

Dendrogram of the inferred hierarchical blocks of the manuscript side, with terminals representing manuscripts. The shaded circles represent the manuscript level () as well as community assignments on increasing levels (). Branch colors represent the block assignment of the highest block level for manuscripts.
