Optimizing self-organizing timbre maps: Two approaches
1997
The effect of using different auditory images and distance metrics on the final configuration of a self-organized timbre map is examined by comparing distance matrices obtained from simulations with a similarity rating matrix, obtained using the same set of stimuli as in the simulations. Two approaches are described. In the static approach, each stimulus is represented as a single multi-component vector. Gradient images, which are intended to represent idealizations of physiological gradient maps in the auditory pathway, are constructed. The optimal auditory image and distance metric, with respect to the similarity rating data, are searched using the gradient method. In the dynamic approach…
The Relationship between Auditory Imagery and Musical Synchronization Abilities in Musicians
2009
Musical ensemble performance requires precise action coordination. To maintain synchrony in the presence of expressive tempo variations, musicians presumably anticipate the sounds that will be produced by their co-performers and coordinate their own anticipated actions with these predictions. Anticipatory auditory images in pitch and time may facilitate such predictions. Two experiments were conducted to examine the contribution of different aspects of auditory imagery abilities to sensorimotor synchronization (SMS) in musicians. In Experiment 1, the acuity of single-tone pitch images was measured by an adjustment method and by adaptive threshold estimation. Different types of finger tappin…
