We present DistlerCorpus, a corpus of Hugo Distler’s Der Jahrkreis op. 5.

This paper reports on an experiment extends a methodology to analyze and compare harmonic progressions at moments of formal segmentation in different styles based on corpora of Roman numeral annotations, and deploys it to the styles of Brazilian choro, Anglophone popular and jazz music.

How many composers are we missing in RISM? What percentage of medieval sources of Gregorian chant have we already cataloged? How many differences in music prints do we expect to find between editions? How large is the coverage of songs from genres of a folk music tradition? And how close are we in estimating the size of the harmonic vocabulary of a large number of composers?

How much are we still missing?

Here, we introduce music-theoretically sensible notions of harmonic distance between chords, that allows us to arrive at more fine-grained results regarding relative influences of different kinds of harmonic relations on diachronic changes.

We introduce a novel perspective on set-class analysis combining the DFT magnitudes with the music visualisation technique of wavescapes.

Here, we analyze more than 40 000 pieces of plainchant to better understand the evolution of modes and pitch distributions in a period of five centuries that saw the development of the Western modal practice.
