Figure Lengend Snippet: ( A ) The mean (top row) and standard deviation (bottom row) of the listeners' responses show the similarity between every pair of instruments for three notes A3, D4 and G#4. Red (values close to 1) indicates high dissimilarity and blue (values close to 0) indicates similarity. ( B ) Timbre similarity is averaged across subjects, musical notes and upper and lower half-matrices, and used for validation of the physiological and computational model. ( C ) Multidimensional scaling (MDS) applied to the human similarity matrix projected over 2 dimensions (shown to correlate with attack time and spectral centroid).
Article Snippet: A standard non-metric MDS was performed (Matlab, the MathWorks).
