Abstract An attractive goal in the study of Gregorian chant melodies is reconstructing unobserved as they may have been transmitted along history chant, especially early notation does not capture pitch exactly. We propose doing this computationally using Ancestral State Reconstruction (ASR) over phylogenetic trees. Bayesian trees shown promise a tool to evolution melodies, by inferring plausible topology transmission. However, inferred cannot be used ASR inputs directly, because are undirected, and their branch lengths conflate time evolutionary rate. therefore first apply Divergence Time Estimation (DTE) separate them represent tree directed form on dimension. Using ASR, we then obtain reconstructions for each ancestral nodes, addition distribution obtained from DTE, thus phylogeny melody with music-historical interpretation. applied method Christmas Vespers dataset, compare results against musicological knowledge reconstructed at Solesmes methods contemporary philology, which shows potential cultural transmission through time.
