Unfortunately we were unable (this time) to export the movie files showing the fixations as the score scrolled, however the data tends to confirm that fixations tend to cluster around the "play-head" of the score. | Unlike the Brahms and Weber, silent revolution (2013) (left) and agilus, mimoid, symmetriad (2013) (below), are both scrolling scores, so the image is just a single frame of the score with the gaze frame data for about 3 minutes superimposed over the top. |
One issue of interest to me in the case of silent revolution, was whether the images would be fixated upon in addition to the notation. This particular reading seems to indicate that they are not directly looked at by the performer. It is an issue that might be more fully revealed by reading the whole score and additionally may be idiosyncratic for each reader.
In transit of venus (2009) (right) different musical parameters (sound shape, pitch, dynamic etc) are distributed across the page and the gaze plot shows that the eye moved frequently between them as expected, at least twice stopping to look at the graphic on the left which does not contain any performance instructions. | The final example is from Improbable Games (2010) (left). This work is laid out (and read) like a traditional score, however each measure is continually "refreshed" with new material. The eye movements appear to be much the same as those for a traditional score. The scroll-bar below each measure indicates the rate at which the music should be read. Since the scroll-bar is not fixated upon directly it may be that the performer is able to follow its position in peripheral vision. |
