Perception of musical tension in short chord sequences: The influence of harmonic function, sensory dissonance, horizontal motion, and musical training
This study investigates the effect of four variables (tonal hierarchies, sensory chordal consonance, horizontal motion, and musical training) on perceived musical tension. Participants were asked to evaluate the tension created by a chord X in sequences of three chords {C major → X → C major} in a C major context key. The X chords could be major or minor triads major-minor seventh, or minor seventh chords built on the 12 notes of the chromatic scale. The data were compared with Krumhansl’s (1990) harmonic hierarchy and with predictions of Lerdahl’s (1988) cognitive theory, Hutchinson and Knopoff’s (1978) and Parncutt’s (1989) sensory-psychoacoustical theories, and the model of horizontal mo…
Looking into the eyes of a conductor performing Lerdahl's “Time after Time”
The eye movements of a conductor were tracked during a performance of Lerdahl's “Time after time”. The analysis of the data revealed that, for most of the time, the conductor was looking at the score, rather than the performers. Most of the score-reading was in anticipation of the music to be played. Micro- and macro-anticipations could be defined, the former being between 2 to 5 seconds in advance, the later being more than 5 seconds in advance. The largest visual anticipations were as long as 10 seconds. The longer anticipations were found to correspond to the occurrence of those thematic cells the conductor considered to be of expressive importance for the piece. This suggests that the …
