  1. Musical Similarity: More perspectives and compound techniques CS 275B/Music 254

  2. Musical similarity • Similarity studies in general • Reductionist approachs • Social cognition • Timbral confounds • Compound search techniques • Cognitive distance metrics • Affective similarity 2013 Eleanor Selfridge-Field

  3. Timbral confounds 2013 Eleanor Selfridge-Field

  4. Reductionist approaches: melodic simplification Target: 3452 (Vertical) 2013 Eleanor Selfridge-Field

  5. Time-span reduction German folksong Substitution of one pitch for each bar Work of Helmut Schaffrath and pupils (Essen) cf. http://www.esac-data.org 2013 Eleanor Selfridge-Field

  6. Time-span reduction German folksong Lerdahl-Jackendoff approach more nuanced Substitution of one pitch for each bar Work of Helmut Schaffrath and pupils (Essen) cf. http://www.esac-data.org 2013 Eleanor Selfridge-Field

  7. Social cognition Morris tune The Folìa Danny Boy 2013 Eleanor Selfridge-Field

  11. Pitch-time space: interval reductions Suk Won Yi, UCLA, (1992) 2013 Eleanor Selfridge-Field

  12. Pitch-time space: Lerdahl, Krumhansl (2007) Values projected vs values judged Tension attraction 2013 Eleanor Selfridge-Field

  13. Prototypical (elusive) melodies Hypothetical melody: Mozart Piano Sonata in G Major Possible reductions Actualities 2013 Eleanor Selfridge-Field

  14. Narmour: Theory of Melody (and melodic implication) If interval < fourth stepwise departure likely If interval  fourth directional change likely Cf. Themefinder refined contour search 2013 Eleanor Selfridge-Field
