Structural Communication in Piano Duos: Musical Compatibility and Individual Differences in Interpretation

Ensemble performance may involve each member contributing to a shared interpretation of the piece. In commercial recordings of piano duo performances, this study examines how individual differences in interpretation between each duo effect the rating of salience of particular events (accents) as well as the continuous ratings of phrasing and tension. An example comparing performances of Mozart’s Sonata KV 448, 3rd movement and Sonata KV521, 2nd movement for duos Argerich and Kissin, and Haebler and Hoffman is shown, looking at significant differences in the ratings of events between the two. More evident differences between ratings of particular events are seen in the KV 448 extract, which may serve to explain some of the variance seen between the average phrasing profiles.
