Time-Varying Spectral Modelling of the Solo Violin Tone

The analysis of the spectrum of a single viol in tone, to better understand how the various partial components contribute to the sound produced, is undertaken. The analysis involves determining which p m1ials are present and how these partials evolve with respect to time. The short-time Fourier t...
