Inner metric analysis
Perceptual evaluation
Music theory Empiric science

• Investigating phenomena immediately related to
  perception and which therefore can be tested with
  the help of empiric interviews

• models of structure of the score (mathematical
  model of metrics)

• Model of perception

• Syntactic/paradigmatic relations between signs
  of the score

• Neutral level (Nattiez)

Analytic Interpretation

• Adorno, Riemann The task of the performer is to
  elucidate the structure of a piece of music to
  the audience, to communicate his understanding of
  the piece to the listener.

• use analytic information as help for decisions
  concerning the performance of the piece

• use resulting performance in listening experiments

Metric Coherence

• correspondence between inner and outer metric
  structure
• presuppositionoccurrence of regularity (weight
  layers corresponding to specific periods)
• a metric subscale of outer metric hierarchy
  significant in the inner metric weight
• phase-coincidence, phase-displacement

David Epstein that the first six measures of
the opening, in their metric organization ...
make unclear whether the music is to be perceived
as 3/4 or as 3/2 (Beyond Orpheus)

Analytic Interpretation

• Metric weights
  Performance
• Do metric weights with a high degree of coherence
  produce performances which express the
  metric structure of the piece more clearly to the
  listener?

Listening experiments

• relationship between metric coherence and the
  understanding of the corresponding interpretation
  by the listeners detected
• metric weights of higher degree of coherence led
  to a more convincing interpretation regarding the
  question in how far the metric structure was
  expressed properly

Analytic Interpretation

• correspondence between perceptual evaluation of
  listeners and the shape of the analytical
  performance --gt relation between model of metric
  structure of the score and the understanding of
  listeners
