Presentation Transcript

  1. Chopin’s mazurka in C-sharp minor (63/3) • Correlation maps • Timescapes / Dynascapes

  2. Correlation Maps – nearest neighbor (from tempo graphs) • Draw one line connecting each performance to its closest correlation match • Correlating to the entire performance length.

  3. Correlation Maps – adding the average • synthetic average generated by averaging duration of each beat in each performance

  16. Correlation • Measures how well two shapes match: Pearson correlation: r = 1.0 is an exact match. r = 0.0 means no relation. output range: -1.0 to +1.0

  19. Closeness to the average

  20. Average tempo over time • Performances of mazurkas slowing down over time: • Slowing down at about 3 BPM/decade Laurence Picken, 1967: “Centeral Asian tunes in the Gagaku tradition” in Festschrift für Walter Wiora. Kassel: Bärenreiter, 545-51.

  21. Average Tempo over time (2) • The slow-down in performance tempos is unrelated to the age of the performer

  22. Absolute Correlation Map

  23. Absolute correlation without average • Correlation maps are showing best correlations for entire performances

  24. Boring timescape pictures over-exposed photographs -- throw them in the waste bin. The same performance by Magaloff on two different CD re-releases: Philips 456 898-2 mazurka 17/4 in A minor Philips 426 817/29-2 • Structures at bottoms due to errors in beat extraction, measuring limits in beat extraction, and correlation graininess.
