| The Essen folk song collection does not include harmony, only monophonic melodies. We added chords ourselves, using a simplistic approach. Namely, the chords change every measure (there is only one chord associated with each measure). We find the suitable chord by creating a pitch class histogram for a measure (which takes into account the duration of the notes that sounded in the measure) and finding the smallest cosine distance with a mask of 24 major and minor chord triads. | The Essen folk song collection does not include harmony, only monophonic melodies.
