This dataset contains information about the internal composition of medieval manuscripts containing tropes sourced from Corpus Troporum. It provides information about which so-called trope elements, snippets that are inserted into the existing plainchant, appear in which manuscripts around the whole of Europe. The trope element indices of the following two volumes are available: * Jacobsson, Ritva Maria. Corpus troporum. 1, Tropes du propre de la messe, 1, Cycle de Noël. Almqvist & Wiksell International, 1975. * Björkvall, Gunilla, Gunilla Iversen, and Ritva Jonsson. Corpus troporum. 3: Tropes du propre de la messe: 2. Cycle de pâques. na, 1982.
