Bach chorales (1b)

Description

This dataset comprises 370 chorales by J. S. Bach.

Details

This dataset was constructed from data downloaded from KernScores. The original KernScores data comprises full polyphonic scores. These scores were converted to chord sequences using the algorithm of \insertCitePardo2002;textualhcorp, with an expanded chord dictionary, and colocating segment boundaries with metrical beat locations as estimated from time signatures.

According to KernScores, these chorales were collected after J. S. Bach's death by his son C. P. E. Bach, and finished by Kirnberger, a student of J. S. Bach, after C. P. E. Bach's death. The KernScores dataset was constructed from the fourth edition of the chorales by Breitkopf & Hartel, c. 1875, entitled "371 four-part chorale chants of Johann Sebastian Bach", retypeset c. 1915 as Edition Breitkopf 10, and reprinted by Associated Music Publishers, Inc., New York in c. 1940.

The dataset uses S3 classes from the hrep package, specifically: pc_chord, for representing chords; vec, for representing chord sequences; corpus, for representing the corpus.

Each chord is represented as a 'pitch-class chord', corresponding to a bass pitch class and a set of non-bass pitch classes.

Note

The dataset excludes number 150, the only chorale not in four parts.
