Summary: | This research seeks to verify the assumption that the presence of vibrato assists
listeners in "hearing" the resonance structure of a violin, hence facilitating
judgments concerning violin timbral quality. Three violins of different costs and
presumably different qualities were used. Listening tests were conducted to
identify the perceived timbral quality of each violin. To further validate the
results, body resonance curves of the violins were analyzed based upon the
location and separation of two major resonance peaks. The results obtained were
compared with those of previous research findings to confirm the quality of each
violin. Spectrum analysis on glissando tones provided data for the plotting of the
resonance curves. A pitch and vibrato detection algorithm using interpolated zero
crossings was tested for its ability 10 accurately extract the quantifiable
parameters of a vibrato. namely its rate and frequency excursion. |
